Question

One Model for the geneti determination of handeness in humans is the random recessive model proposed by Amar Klar. in this model, recessive homozygotes (rr) are equally likely to be right handed or left handed, where as those with the dominant phenotype (Rr or RR) are right handed. suppose this model is true and that mating is random with respect to this locus. What is the frequency of th R allel in a population where 94% are right handed?

Using this model would you expect the frequency of left handedness to be affected by the inbreeding coefficient, F? if so how?   

a) The frequency of left handedness would not be affected by changes in F

b) the frequency of left handedness would increase with increases in F

c)  the frequency of left handedness would decrease with increases in F

Explanation / Answer

1. The frequency of the R allele will remain the same in matting with random population.

2. The frequency of left handedness would decrease with increase in F. Because when right handed frequency increase the left handed frequency will decrease.
