You asked: What is an individual with the genotype AA?

A homozygous dominant (AA) individual has a normal phenotype and no risk of abnormal offspring. A homozygous recessive individual has an abnormal phenotype and is guaranteed to pass the abnormal gene onto offspring.

What gametes can an individual with genotype AA make?

A heterozygous individual has two different alleles. Therefore it would have the genotype Aa. An individual with the genotype Aa can make two types of gametes: A and a. Since this is a random process, the individual will, on average, make equal numbers of each gamete.

Is genotype AA homozygous?

A homozygous genotype means that you have two of the same alleles, which are represented by the letters A or a. So if an individual has AA or aa, we say they are homozygous.

What gametes can be produced by AA?

The number of gametes produced by a specific genotype is calculated by the formula 2n, where n= number of heterogeneous alleles present in the genotype. Here, the given genotype consists of two heterogeneous alleles Aa and Bb while CC is homozygous. So, it can produce 22 = 4 types of gametes.

What is the phenotype for the genotype AA?

An Aa genotype can result in the same phenotype as either an AA or aa genotype, if one of the alleles acts in a dominant fashion. If the A allele is dominant over the a allele, then the phenotype of a heterozygous (Aa) individual will be the same as the phenotype of a homozygous dominant (AA) individual.

How many phenotypes can be expressed?

There are three common alleles in the ABO system. These alleles segregate and assort into six genotypes, as shown in Table 1. As Table 1 indicates, only four phenotypes result from the six possible ABO genotypes.

Is AA compatible with AS?

Compatible genotypes for marriage are:

AA marries an AS. You’ll end up with kids with AA and AS which is good. But sometimes if you’re not lucky all the kids will be AS which limits their choice of partner. AS and AS should not marry, there is every chance of having a child with SS.

Is AA homozygous or heterozygous?

Two dominant alleles (AA) or two recessive alleles (aa) are homozygous. One dominant allele and one recessive allele (Aa) is heterozygous.

What are the two possible gametes produced by a plant that has the genotype AA?

What are the two possible gametes produced by a plant that has the genotype Aa? Give the probability of each type of gamete. The two possible gametes that are produced by the genotype Aa would be “A” and “a”.
