Explanation:
Detailed explanation-1: -The physical appearance of an organism with respect to a trait, i.e. yellow (Y) or green (y) seeds in garden peas. The dominant trait is normally represented with a capital letter, and the recessive trait with the same lower case letter.
Detailed explanation-2: -We’ll use letters to represent alleles. Capital “A” will represent the yellow pea allele and lowercase “a” will represent the green pea allele. The yellow pea phenotype has a genotype of AA. The green pea phenotype has a genotype of aa.
