Which of the following is correct statement?
A. Reproduction alone does not alter allelic or genotypic frequencies from generation to generation
B. Frequency of the heterozygote is always greatest when allelic frequencies are range between .33 and .66
C. Inbreeding is more likely to take place in nature when population size becomes very small and the number of mates is limited.
D. The movement of a few individuals between populations can counteract the effects of genetic drift

Consider an autosomal locus with two alleles A1 and A2 at frequencies of 0.6 and 0.4 respectively. Each generation, A1 mutates to A2 at a rate of μ = 1 x 10-2 while A2 mutates to A1 at a rate of υ = 1 x 10-1) Assume that the population is infinitely large and no other evolutionary force is acting. The overall change in allelic frequency will be

#Unit 11. Evolution and Behavior
The frequencies of two allele’s p and q for a gene locus in a population at Hardy-Weinberg equilibrium are 0.6 and 0.4, respectively. After a few generations of inbreeding, the heterozygote frequency was found to be 0.10, The inbreeding coefficient in this case is

B) These behavior is increases the individual fitness of both the donor and the recipient
C) Overall increase the inclusive fitness of the population
D) These behavior depend on genetic relation
