(a) aa (b) bb (c) cd (d) ee, which of these is not a phenotype? A homozygous genotype has two identical alleles (e.g., bb or rr). Heterozygous is a term used in genetics to describe when two variations of a gene, known as alleles, are paired at the same location (locus) on a chromosome

By contrast, homozygous is when there are two copies of the same allele at the same locus.
Heterozygous refers to having different alleles for a particular trait
If the two versions are different, you have a heterozygous genotype for that gene The relationship between the two alleles affects which traits are expressed. Thus, the genotypes that are heterozygous in this list are a (aa) and c (zz) These genotypes fit the criteria of having two different alleles for a gene
For instance, in pea plants, the allele for tall plants (t) is dominant over the allele for short plants (t). Which of mendel's findings does her test cross illustrate? The presence of different alleles at the same locus characterizes heterozygosity, which can result in the expression of the dominant trait due to the masking effect of the dominant allele. If you have two copies of the same version of a gene, you are homozygous for that gene
If you have two different versions of a gene, you are heterozygous for that gene.
For every gene, you inherit two alleles One from your biological father and one from your biological mother Together, these alleles are called a genotype If the two versions are different, you.
To solve this question, we need to identify which genotypes are heterozygous and which are homozygous A heterozygous genotype has two different alleles (e.g., bb)
