Homozygous means "the same egg." That refers to identical twins. Identical twins are always the same gender since they have the same chromosomes.
A homozygote is a homozygous organism. An organism can be a heterozygote or a homozygote. "Hetero" means different and "Homo" means the same.
Homozygous is a term used to describe an organism that has two of the same alleles for a trait. If a person's alleles for eye color are BB (dominant dominant) or bb (recessive recessive), they are homozygous.
homozygous = AA & AA Heterozygous = Aa
homozygous dominant means two alleles that are the same that are capital letters, heterozygous recessive means that to alleles are different BUT the same letters in lower case. (alleles for gender) EX: TT, Tt is homozygous dominant tt, tt is heterozgous recessive

A pair of alleles which are the same are said to be homozygous.
Homozygous means "same" so a homozygous recessive trait would be a same [with parents] trait that is not the stronger trait which is dominant. Dominant is stronger showing trait, recessive is weaker trait. If you are dealing with Punnett squares then tt is homozygous recessive and TT is homozygous dominant. Hope this helped...
The two AA genes are the same uppercase letter, so they are homozygous. 'Homo' means 'same'. If the genotype was Aa, it would be heterozygous, because 'hetero' means 'different'.
