1)A Quarter Horse breeder has a stallion that they suspect may have had a parent that was dual registered in the paint herdbook. Although rare, it is possible for a solid coloured stallion to carry the lethal white overo allele. In order to test the...

1) With the following observed gametic frequencies (which are in linkage disequilibrium), what is the frequency of the AB gamete type at equilibrium? f(AB) = 0.07 f(Ab) = 0.21 f(aB) = 0.10 and f(ab) = the remainder. Hint : The frequency of the AB gamete type at equilibrium is the observed frequency...

1) As a result of genotyping two loci (A and B) in a large number of progeny of two heterozygous individuals, a researcher has determined that the gametes produced by one of the parents had the following frequencies: f(AB) = 0.30, f(Ab) = 0.24, f(aB) = 0.09, and f(ab) were the...

Q1) Suppose a researcher collects seeds and pollen (i.e. gametes) from a certain kind of plant. If 264 gametes are AB, 66 are Ab, 176 are aB and 44 are ab, what is the frequency of the A and b alleles (to 1 decimal place)? 1) f(A) = 0.5 and f(b)...
