Let P be a probability function on a sample space S. Suppose A, B S such that P(A) = .59, P(B) = .50, and P(A B) = .28. (A) Find P(A\'). (B) Find P(B - A). (C) Find P(A B). (D) Find P(A\' B\').

Solution

the genetic composition of F1 hybrid will be CeWiBr

(were e, i, r are the mutant alleles of coral eye, wrinkled wings and bronze body respectively.)

The gamete formation in F1 generation will be as under

CWB----354

CWr---156

CiB---86

Cir----22

eWB---18

eWr---93

eiB---157

eir--362

1) the answer is none of the above three mutant alleles (a-c) are domnant.

Beacuse in presence of the dominant allele the mutant allele remains recessive. I.e., F1 generation normal.

2) None of the above three mutant alleles (a-c) are X-linked.

the data does not shows the number of male and female in the F2 generation.

3) There are three loci heterozygous in the F1 generation, according to above data.

I.e., the F1 generation has genetype of CeWiBr.

5) Yes, genes are linked because the test cross ratio varies from the expected ratio.

and the order is (c) coral-wrinkled-bronze. As the frequency of coral-wrinkled and wrinkled-bronze are higher than coral-bronze.
