Phenotypic frequency formula
WebFeb 7, 2024 · Phenotypic ratio: A : a = 3 : 1 Because allele a is recessive, when it appears with a dominant allele, the trait it carries is not visible, but the allele is still there, ready to potentially be inherited in the future. Autosomal alles - homozygous or heterozygous?
