Question

What does homozygous describe?

Answer 1

When both parents contribute the dominant gene for a specific trait...call it X for now...you get XX or homozygous dominance for that trait (assuming complete dominance)

When one parent contributes a dominant gene for that trait, and the other contributes a recessive gene for that trait....the result is Xx or heterozygous dominant for that trait.

Answer 2

Hi,

Homozygous means that one has identical alleles for a single trait. An allele is one of many different forms of a gene that occupies a given locus (location) on a chromosome. For example, there are many different alleles for for hair texture texture. If H stands for curly hair and h stands for straight hair, then either HH or hh would be considered homozygous. Hh would be heterozygous.

Answer 3

In indicates that a diploid organism has to copies of the same allele for a particular gene. That is that their genotype is AA or aa, but NOT Aa. That last combination is a heterozygote.
