Need ! extra ! complete the punnett square for the cross between two plants that are heterozygous for seed shape (ss) and seed color (gg). smooth is dominant to wrinkled and green is dominant to yellow. determine the phenotypic ratio for the offspring by determining the number of each of the phenotype combinations listed below.

parental phenotypes: x
parental genotypes: x
parental gametes: x

Joe is breeding cockroaches in his dorm room. he finds that the average wing length in his population of cockroaches is 4 cm. he chooses the six cockroaches that have the largest wings; the average wing length among these selected cockroaches is 10 cm. joe interbreeds these selected cockroaches. from earlier studies, he knows that the narrow-sense heritability for wing length in his population of cockroaches is 0.6. a. calculate the selection differential and expected response to selection for wing length in these cockroaches. b. what should be the average wing length of the progeny of the selected cockroaches?
