Locus A has two alleles (A and a) while locus B has two alleles (B and b). The recombination frequency between locus A and locus B is 11%. A F1 heterozygote in trans configuration is mated with an aabb individual. What are the expected phenotypic percentages in the resulting progeny? Report your percentages to the tenths place and in the following format, replacing the "0.0" with your percentages.

Expert Solution

Answer - Recombination frequency between locus A and locus B is 11%.

       Trans configuration is mated with an aabb individual.

F1                  A----------b      a--------b
                                          X
                       a----------B      a--------b

Gametes
          A--------b a----------B A--------B a-------b   X a------b

The recombination frequency is 11%. So A--------B and a-------b are recombinant.

Recombinant progeny = 11

Total progeny = 100

Therefore 11/100 = 0.11

Remaining are parent = 89. 89/2 = 44.5.

Parent A--------b = 44.5 = 44.5% or 0.445

Parent a----------B = 44.5 = 44.5% or 0.445

Recombinant offspring A--------B = 5.5% or 0.55

Recombinant offspring a-------b = 5.5% or 0.55

Consider a locus with two alleles - B and b. B is dominant, while b is recessive. There is no mutation. B has a selective advantage relative to b, so that the fitnesses of the three genotypes are BB = 1, Bb = 1, and bb = 1-s. In this case, s = 0.50, so that bb homozygotes have 50% fitness of heterozygotes and BB homozygotes. If the population has the following genotypic counts prior to selection of BB =...

Let A and B represent two variants (alleles) of the DNA at a certain genome locus (chromosome location). Assume that 40% of all the alleles in a certain population are type A and 30% are type B. The locus is said to be in Hardy-Weinberg equilibrium if the proportion of organisms that are of type AB is (0.40)(0.30) = 0.12 (in other words, alleles A and B are independent). In a sample of 300 organisms, 42 are of type AB....
