Concept

Problem: Which approach to determining the likelihood of various genotypes occurring in the offspring of particular parents is easier for you-constructing a Punnett square, or using the product rule to calculate probabilities? Compare and contrast the inheritance patterns of autosomal recessive and autosomal dominant traits.

FREE Expert Solution

In calculating the probability of the genotype in a given cross, using the product rule is easier and faster to use. By using the product rule, you can directly get the probability of a specific genotypes unlike in Punnett square method, wherein you have to write the genotypes and phenotypes of all the progeny to calculate their frequency.
