Question

How do I determine the genotype of the phenotypes given?

Answer 1

the genotype are the symbols to represent the two genes that determine a trait. The genotype is represented by two letters - capital and lowercase. If the phenotype is the recessive trait, the genotype would be represented by two lowercase letters. If the phenotype is the dominant trait, the genotype could be two capital letters or one capital letter and one small letter. Example - tall stems are dominant over short. Dominant could be TT or Tt. Short stems would be tt.
