Question

A wild-type fruit fly (heterozygous for gray body color and red eyes) is mated with a black fruit fly with purple eyes. The offspring are wild-type, 721; black purple, 751; gray purple, 49; black red, 45. What is the recombination frequency between these genes for body color and eye color? Using information from problem 3, what fruit flies (genotypes and phenotypes) would you mate to determine the order of the body color, wing size, and eye color genes on the chromosome?

Accepted Answer

Hello everyone here we have a question asking to determine the order of body color. Wing size and eye color genes on the chromosome of Drosophila, which of the following sets of crosses will you perform a cross one wild type hetero sickness for normal wings and red eyes with a female recessive homesickness for vestigial wings and purple eyes. Cross to male wild type hetero sickness for gray body and red eyes with a female recessive home azaleas for black body and purple eyes be cross one male wild type homo zegas for normal wings and red eyes with female recessive homos I guess for vestigial wings and purple eyes. Cross to male wild type homos I guess for gray body and red eyes with female recessive Homans I guess for black body and purple eyes. See cross one Wild type hetero ziggy's from normal wings and red eyes with female recessive homesickness for vestigial wings and purple eyes. Cross to male wild type home azaleas for gray body and red eyes with female recessive homesickness for black body and purple eyes or D cross. One male recessive homos ideas for vestigial wings and purple eyes with female recessive homo zegas for vestigial wings and purple eyes. Cross to male recessive homo zegas for black body and purple eyes with female recessive homogeneous for black body and purple eyes. And our answer here is a cross one male wild type Hetero ziggy's for normal wings and red eyes with female recessive homesickness for vestigial wings and purple eyes. Cross to male wild type heterosexuals for gray body and red eyes with female recessive homesickness for black body and purple eyes. And that's because it includes all of our options. So that will help us determine the order of body color, wing size and eye color. Thank you for watching. Bye.
