AP BIOLOGY

Detailed explanation-1: -Since there are recessive offspring, the white parent must have carried the recessive allele and therefore had the heterozygous genotype, Ww.

Detailed explanation-2: -The genotype is represented by letter combinations, such as TT, Tt, and tt . When an organism has two of the same alleles for a specific gene, it is homozygous (homo-means “same") for that gene. An organism can be either homozygous dominant ( TT ) or homozygous recessive ( tt ).

Detailed explanation-3: -The different types of genotypes are-homozygous recessive (pp), homozygous dominant (PP), and heterozygous (Pp). The homozygous dominant and the heterozygous genotypes show the same phenotypes.

Detailed explanation-4: -Genotype = genes present in an organism (usually abbreviated as two letters) TT = homozygous = pure. Tt = heterozygous = hybrid.
