Yellow body color (y), crossveinless wings(cv) and forkedbristles (f) are all recessive and in that order on the Xchromosome in Drosophila. Yellow is 14 map units from crossveinlessand crossveinless is 22 map units from forked. A yellow,crossveinless female is crossed to a forked male. An F1 female istestcrossed to a male expressing all three traits. If thecoefficient of coincidence is 0.9, how many completely wild typeflies will be observed out of 1000?
From the same testcross, how many flies will express forkedonly?
How many flies expressing yellow only will be observed?
Please explain and show work.
