Both parents are aa: All of their children will be aa as well (homozygous for aa). One parent is Aa and another parent is Aa: Their child has a 25% chance of being AA (homozygous), a 50% chance of being Aa (heterozygous), and a 25% chance of being aa (homozygous) One parent ...
Alternative forms of a given gene are called alleles, and they can be dominant or recessive. When an individual has two of the same allele, whether dominant or recessive, they are homozygous. Read Homozygous vs. Heterozygous | Definition & Differences Lesson ...

Allele pairs are described using the terms heterozygous and homozygous. Every diploid entity comprises two copies of each of the genes, wherein each could be recessive or dominant. Dominant alleles are expressed to give rise to a phenotype, whereas the recessive alleles remain unexpressed. Both the...

Heterozygous vs. Homozygous An individual that ishomozygousfor a trait has alleles that are similar. Unlike heterozygous individuals with different alleles, homozygotes produce only homozygous offspring. These offspring may be either homozygous dominant(RR)or homozygous recessive(rr)for a trait. They may...
