Question

Punnett squares provide an easy way6 to predict the possible genotypes for an offspring, but it is not practical to perform a Punnett square analysis on all possible combinations of all members of a population to predict what the population might look like in the future. For that we muse return to statistics. They Hardy-Weinberg equation is a tool biologists use to make predictions about a population and to show whether or not evolution is occurring in that population. How many mating pairs are illustrated in Model 1? Describe the parents in each mating pair in Model 1. Use terms such as homozygous, heterozygous, dominant, and recessive. Use two Punnett squares to determine the possible genotypes for offspring from the pairs.

Explanation / Answer

1) There are 4 mating pairs

2) The given diagram are all Punnet square In monohybrid cross it shows homozygous or heterozygous,In dihybrid cross it shows dominant or recessive.

3) Two punnett square to determine the possible genotypes for offspring from the pairs are-

b b

B Bb Bb

b bb bb

genotypes for punnet square are 50% (B/b) and 50%(b/b).
