1. In Eastern toads, biologists may consider two traits that are independently assorted: B=bumpy skin/b=smooth skin and E=webbed feet, e=non- webbed feet. Two toads, who are each heterozygous for both traits, are mated. Complete a Punnett square to show the potential inheritance of these traits among the offspring. Record the ratio in which each phenotype is likely to occur in the next generation.

Transcribed Image Text:In the mating of the two individuals from the previous question, the
resulting offspring (556 total toads) phenotypes were recorded below.
Complete a Chi Squared Goodness of Fit test to see if the observed data
fits the expected ratio (from the punnet square in question 1).
