There are two alleles at the J locus: J 1
and J 2
⋅J 2
is the less desirable allele-in homozygous form it is lethal-and its frequency in the current generation is .2. What will be the frequency of J 2
in the next generation if: a. with respect to fitness, J 1
is completely dominant to J 2
? b. J 2
is partially dominant such that J 1
J 2
individuals produce 70% fewer offspring than J 1
J 1
types? c. Compare your results for (a) and (b) above and explain why they differ.
