Alleles
The different forms of genes, represented by letters.
Dominant traits
capital letter. Inherited characteristics from parents’ dominant alleles that appear on offspring.
Recessive Traits
lowercase letters. inherited characteristics that form parents’ when both have recessive alleles that appear on offspring.
Genotype
The two alleles that represent the genetic makeup of the offspring. (TT- Tt- tt)
Phenotype

Homozygous
alleles are the same. (both dominant or both recessive).
Heterozygous
alleles are different. (Dominant trait is visible but carries recessive) (Tt)
