4. In Drosophilia, the allele b gives black body (wild type is b+ or brown), and at a different gene locus, the allele cn gives cinnabar eyes (wild type eyes are cn+ or red.) A female which is heterozygous for both genes is testcrossed. [A testcross is a mating ma ly that is homozvgous for all recessive mutant traits. a male, homozygous for black and cinnabar.J Male: b b/cn cn In this case, the fly is Female b b+/cn cn+ The following progeny are observed: 53 brown body, red eyes 50 black body, cinnabar eyes A. Write the genotypes of each class of progeny. 451 brown body, cinnabar eyes 446 blackbody, red eyes the fomawo most common groups of progeny each bear one of the parental chromosomes from Lemale. (Remember the two parental chromosomes segregate during gamete formation.) on the two chromosomes from the female. prane two least common groups of progeny represent recombination events during meiosis. Draw which alleles are present on the recombined chromosomes. D. Calculate the percent of recombinants in this cross. between genes. Draw which alleles are This is a measure of distance Each 1% is called one map unit.
