WebNov 20, 2024 · Explanation: From the Punnet square, there are 2 heterozygous genotypes out of 4 offspring, hence, the probability that an offspring will have a heterozygous genotype is 1/2 or 50%. There are no homozygous dominant genotype among the genotype of the offspring as seen in the Punnet square. WebThere are 210 individuals with the genotype DD, 245 individuals with the genotype Dd and 45 individuals with the genotype dd. Find: the frequency of the dominant and recessive alleles and the frequency of individuals with dominant, heterozygous, and recessive traits. 7.
