Dominant
Gene that shows a strong effect in either the homozygous or heterozygous condition
Recessive
One that shows effects only in the homozygous condition
Heterozygous
Having two unlike genes for a given trait
Homozygous
Having two identical genes for a given characteristic
Ribonucleic acid RNA
A single-strand chemical; Base order= adenine, guanine, cytosine, and uracil
Deoxyribonucleic acid DNA

Sex-linked genes | Genes on either the X or Y chromosome; Female = XX; Male = XY |
Autosomal genes | All chromosomes other that X and Y |
Sex-limited genes | A gene that exerts its effects primarily in one sex because of activation by androgens or estrogens, although members of both sexes may have the gene; Present in both sexes but active mainly in one sex |
