Which plants in this figure must all be heterozygous?
This question can be a little tricky to answer, but, in general, any plant that possesses two different alleles for a particular trait must be heterozygous. This is because, by definition, heterozygosity is the condition of having two different alleles for a particular gene. In the plants pictured, there are four different alleles for the plants' coloration. Two of the plants are heterozygous for coloration, while the other two are homozygous. The two heterozygous plants are the ones in the middle, with one blue allele and one purple allele. The two homozygous plants are the ones on the ends, with either two blue alleles or two purple alleles.

What is the probability that two heterozygous plants will produce a homozygous offspring?
When two heterozygous plants breed, the probability of producing a homozygous offspring is 1/4, or 25%. This is because there are four possible combinations of allele pairs that can occur when breeding heterozygous plants: HH, HT, TH, and TT. Of these four combinations, only TT produces homozygous offspring. Therefore, the probability of two heterozygous plants producing a homozygous offspring is 1/4, or 25%.

What is the probability that two heterozygous plants will produce a heterozygous offspring?
In order to answer this question, we must first understand what it means to be heterozygous. A heterozygous plant is one that has two different alleles for a particular gene. For example, one allele might code for a red flower color, while the other codes for a white flower color. If we assume that the plants are self-fertilizing, then we can say that each plant has a 50% chance of producing a red flower and a 50% chance of producing a white flower. Now, let's assume that we have two heterozygous plants, each with a 50% chance of producing a red flower and a 50% chance of producing a white flower. When these plants produce offspring, we can say that there is a 50% chance that the offspring will inherit the red allele from one parent and the white allele from the other parent. This would result in the offspring being heterozygous just like the parents. Therefore, the probability that two heterozygous plants will produce a heterozygous offspring is 50%.

What is the probability that a heterozygous plant will produce a homozygous offspring?
The probability that a heterozygous plant will produce a homozygous offspring is 1 in 4, or 25%. This is because when two heterozygous plants reproduce, they can produce two different types of offspring: homozygous recessive or homozygous dominant. There is a 50% chance of producing either type of offspring. However, because there are two possible types of offspring, the probability that a heterozygous plant will produce a homozygous offspring is 25%.

What is the probability that a heterozygous plant will produce a heterozygous offspring?
When two plants with different genetic makeup (phenotypes) mate, their offspring will inherit a mixture of the parents' genes (genotypes). The probability that a heterozygous plant will produce a heterozygous offspring is 1:1, or 50%.
If we consider two parents with different genotypes, say Aa and Bb, the possible gametes they can produce are:
Aa → A or a
Bb → B or b
These gametes can then combine to produce the following genotypes:
AB, Ab, aB, or ab
Since each gamete has a 1/2 chance of being produced, and there are two possible gametes for each parent, the probability that any given genotype will be produced is 1/4. So, the probability of an offspring being heterozygous (Aa x Bb) is 1/4.
In other words, if we start with two heterozygous plants (Aa x Bb), we can expect that 25% of their offspring will be homozygous AA, 50% will be heterozygous AaBb, and 25% will be homozygous BB.

What is the probability that a homozygous plant will produce a homozygous offspring?
A homozygous plant is one that has two identical alleles for a particular gene. The probability that a homozygous plant will produce a homozygous offspring depends on how the alleles are combined.
If the alleles are combined such that each parent contributes one allele to the offspring, then the offspring will be heterozygous and the probability of producing a homozygous offspring is zero. If the alleles are combined such that both parent contribute the same allele to the offspring, then the offspring will be homozygous and the probability of producing a homozygous offspring is one.
In order for a homozygous plant to produce a homozygous offspring, the alleles must be combined such that both parent contribute the same allele to the offspring. The probability of this happening is one.

What is the probability that a homozygous plant will produce a heterozygous offspring?
There is a fifty percent (50%) chance that a homozygous plant will produce heterozygous offspring. This is because when a sperm fertilizes an egg, it randomizes which allele it will give to the offspring. So for each "pair" of alleles, there is a 25% chance that the offspring will inherit one allele from each parent (making it heterozygous), a 50% chance that it will inherit two alleles from one parent (making it either homozygous dominant or homozygous recessive), and a 25% chance that it will inherit two alleles from the other parent (also making it either homozygous dominant or homozygous recessive).

What is the probability that a heterozygous plant will produce a plant with the same phenotype?
A heterozygous plant is one that has two different alleles for a given trait. For example, a plant that is heterozygous for the trait of flower color might have one allele for red flowers and one allele for white flowers. The probability that a heterozygous plant will produce a plant with the same phenotype is 50%. This is because each time the plant produces a seed, there is a 50% chance that the seed will inherit the allele for red flowers and a 50% chance that the seed will inherit the allele for white flowers.

What is the probability that a heterozygous plant will produce a plant with a different phenotype?
A heterozygous plant is one that has two different alleles for a particular trait. For example, a plant with the alleles for red and white flowers is heterozygous for flower color. The probability that a heterozygous plant will produce a plant with a different phenotype depends on what the other allele is. If the other allele is for blue flowers, then the probability that the heterozygous plant will produce a plant with a different phenotype is 50%. This is because there is a 1 in 4 chance that the plant will inherit the blue allele from the other parent plant, and thus produce a blue-flowered plant. If the other allele is for a different trait, such as leaf shape, then the probability of the heterozygous plant producing a plant with a different phenotype is 0%.

What is the probability that a homozygous plant will produce a plant with the same phenotype?
Phenotypic traits are determined by an individual's genotype, which is the complete set of genetic instructions for building and maintaining that organism. For example, the genotype for tallness in humans consists of a pair of alleles, one inherited from each parent. If both alleles coding for tallness are present (homozygous), then the individual will be tall. However, if only one allele for tallness is present (heterozygous), then the individual will be of average height.
The probability that a homozygous plant will produce a plant with the same phenotype is 100%. This is because the phenotype is determined by the genotype and the genotype is not affected by the environment.

What is the difference between homozygous and heterozygous traits?
Heterozygous traits can have different outcomes due to the combination of their alleles. For example, a person might be heterozygous for a trait that makes them tall but also be heterozygous for a trait that makes them short. Depending on which allele is dominant (has a higher frequency), either the tall or the short phenotype might develop. This means that one person could have two different geneticmakeups for height and could end up being anywhere from moderately tall to exceptionally tall or from moderately short to extraordinarily short, depending on the combination of their alleles. There is no such thing as a “wildtype” when it comes to genes - every individual has a unique mix of alleles for any given trait.
What is the difference between diploid and heterozygous?
Diploid organisms have two identical copies of each gene. Heterozygous is a state where each allele of a particular gene is different; one of the alleles is recessive and the other is dominant.
What is the meaning of homozygous?
The meaning of homozygous is “containing two identical copies of a gene.”

What are some examples of heterozygous genotypes?
heterozygous in red-green color blindness; heterozygous in wild type and mutant alleles of a gene that causes Huntington's disease.
What are homozygous and heterozygous alleles?
Heterozygosity is a genetic condition where an individual has two different alleles for a particular gene (i.e., two different versions of the gene). Heterozygotes have two different versions of the gene in each cell. Heterozygotes are said to be “paired” because they have two differently shaped versions of a chromosome (one from their father and one from their mother). This pairing occurs during meiosis, the process by which haploid cells divide to form pairs of daughter cells.
