Two pure-breeding strains of flies are mated, and the F1 are intercrossed. The first strain has curled wings and black bodies. The second strain has straight wings and brown bodies. The F2 progeny are 271 straight wings with brown bodies, 31 curled wings with black bodies, 94 curled wings with brown bodies and 90 straight wings with black bodies. If the F1 were backcrossed to the straight, wing brown bodied parent, what phenotypes would be produced among the progeny? What would be the proportion of each phenotype?

In an autotetraploid Chinese primrose (Primula sinensis), the gene controlling stigma color is very near the centromere of the chromosome carrying it. The allele G for green stigma is dominant to g for red stigmas. A homozygous green autotetraploid strain is crossed with a homozygous red autotetraploid strain. a. What phenotypic ratio of green to red is expected if: The F1’s are intercrossed? The F1’s are crossed with red plants
Female fruit flies from a true-breeding strain with yellow body and cut wings are mated to male fruit flies from a true breeding strain that is wild type for both body color and wings. In the F1 generation, all of the female flies are wild type for both characters while all of the male flies have yellow bodies and cut wings. The F1 males and females are intercrossed, and among 1000 male progeny the following is observed: 425 yellow body and cut wings 405 wild type body and wild type wings 90 yellow body and wild type wings 80 wild type body and cut wings Are these genes X-linked or autosomal? How far apart are they from each other?
