PATHOLOGY

Detailed explanation-1: -A Punnett square is a chart that allows you to determine the expected percentages of different genotypes in the offspring of two parents.

Detailed explanation-2: -The Punnett square is a table in which all of the possible outcomes for a genetic cross between two individuals with known genotypes are given.

Detailed explanation-3: -Answer and Explanation: Punnett’s square is a very important part of genetic studies. It allows the representation of allelic interaction and inheritance of traits from parental pairs of alleles. Therefore, the correct answer is (a) example of all possible combinations of alleles.

Detailed explanation-4: -The Punnett square is a tabular summary of possible combinations of maternal alleles with paternal alleles. These tables can be used to examine the genotypical outcome probabilities of the offspring of a single trait (allele), or when crossing multiple traits from the parents.
