What is a homozygous dominate?

Answer:
Homozygous dominate refers to two alleles from a parental generation that are the same (not Heterozygous) and also dominant (not recessive). Let's set up a Punnett square for an example.

.... (P) (p)
(P)|PP Pp
(p)|Pp pp

Notice here that we have two Homozygous allele pairs and two Heterozygous allele pairs. Upper-case bold "PP" refers to the Homozygous dominant alleles and the lower-case italicized "pp" refers to the Homozygous recessive alleles. The allele pairs with both a dominant trait and a recessive trait (Pp) are said to be Heterozygous - the opposite of Homozygous.
