NEET BIOLOGY

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. A Punnett square allows the prediction of the percentages of phenotypes in the offspring of a cross from known genotypes.

Detailed explanation-2: -The correct answer is: Punnett square.

Detailed explanation-3: -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.

Detailed explanation-4: -When conducting a cross, one way of showing the potential combinations of parental alleles in the offspring is to align the alleles in a grid called a Punnett square, which functions in a manner similar to a multiplication table (Figure 5). Figure 6: Each parent contributes one allele to each of its offspring.

Detailed explanation-5: -A Punnett square shows the probability of an offspring with a given genotype resulting from a cross. It does not show actual offspring.
