Colorblindness is a sex-linked (X-linked) recessive genetic disorder. Cross a female that is homozygous recessive for colorblindness (XcXc) with a normal-vision male (XCY), and determine, assuming the parents have a son, the percent chance of having a normal vision son: You may use a scratch sheet of paper for all scratch work.

In chickens, red feathers (R) are dominant to brown feathers (r). If a homozygous dominant red feathered chicken (RR) is crossed with a homozygous recessive brown feathered chicken (rr), what is the percent chance of having a chicken with brown feathers? (ASSUME AUTOSOMAL, COMPLETE DOMINANCE INHERITANCE). You may use a scratch sheet of paper for all scratch work.

In fruit flies, long wings (L) are dominant to short wings (l). If a fruit fly heterozygous for long wings (Ll) is crossed with a fruit fly that is homozygous recessive for short wings (ll), what is the percent change of having a heterozygous offspring? (ASSUME AUTOSOMAL, COMPLETE DOMINANCE INHERITANCE). You may use a scratch sheet of paper for all scratch work.
