Question
Chapter 14.2, Problem 1CC
Summary Introduction
To determine: The proportion of homozygous dominant, homozygous recessive, and heterozygous offspring after AA × Aa genetic cross.
Concept introduction:
During gamete formation, two alleles of a gene segregate into different gametes. This is based on the Mendel’s law of segregation. After the genetic cross, the possible allele combinations are predicted, which determines the genotype of the offspring. The offspring can be homozygous dominant (both alleles are dominant), homozygous recessive (both alleles are recessive), or heterozygous (one dominant and one recessive allele).
