Question

Suppose that alleles for eye color for a certain male fruit fly are (R,W) and all the alleles for eye color of the mating female fruit fly are (R,W), where R and W represent red and white respectively. Their offspring will recieve one allele from each parent.

A. Define the sample space of the allelesfor eye color for offspring

B. Assume each of the four outcomes has equal probability. If an offspring ends up with either two white alleles or a red and a white allele, it's eyes will look white. Given that the offsprings eyes look white, what is the conditional probabilty that it has two white alleles for eye color?

Explanation / Answer

Sample space for the offspring S:

S: { (RR, RW, WR, WW) }

P( White alleles | white eyes)

now, P (White eyes) = { WR, RW , WW}

P( White alleles | white eyes) = 1 / 3

hope this helps.
