Introduction to Genetics
By: Emily Hess
Homozygous- The two alleles (genes) for a trait are the same (Ex: HH & hh)
Dominant- The allele that masks or hides the recessive allele (uppercase letter)
Recessive- The allele that is masked or hidden by the recessive allele (lowercase letter)
Genotype- Gene combination
Phenotype- physical appearance/expression of a trait
Heterozygous vs. Homozygous
All the possible offspring of the two parents would be Heterozygous. (One Dominate and one Recessive gene.) The Dominant gene would be expressed.
The parents and the offspring would all be Homozygous. They are all recessive genes.
