Genetic linkage is a phenomenon where two genes exist close to each other on the same chromosome. ... In addition, when a single trait is determined by multiple genes and the effect of each of these genes is graded, Punnett squares cannot accurately predict the distribution of phenotypes in the offspring.
Explanation:
Genetic linkage is a phenomenon where two genes exist close to each other on the same chromosome. ... In addition, when a single trait is determined by multiple genes and the effect of each of these genes is graded, Punnett squares cannot accurately predict the distribution of phenotypes in the offspring.
A punnet square is a chart that shows all the possible combinations of alleles that can result from a genetic cross. If you know the parents' alleles for a trait, how can you use a punnet square to predict the probable genotype of the offspring. A pea plant with round seeds has the genotype Rr
