Q1. Imagine that you perform fruit fly crosses with dissimilar pairs of three X-linked traits specified by genes x, y, and z. You observe recombinant frequencies for the various gene pairs: xy= 6.9% yz= 7.6% xz= 0.7% what is the most possible gene order?

Q2. Last year's survey of squirrels from around the campus found a large number of squirrels with different tail types that may or may not be a polymorphic trait. There were 229 squirrels with flat tails and 262 squirrels with bushy tails. Assuming that genotype essential to produce flat tails is homozygous recessive (such as bb) compute the frequency of the b allele in the squirrel population to two decimal places.
