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

polymorphism is define existence of two or more form of same species within same population at the same time and place .polymorphism either balanced or transient depending upon type of natural selection  which of the following reason for balanced genetic polymorphism

#Unit 11. Evolution and Behavior

A source population with allelic frequency of p and q is .90 and .10 respectively. Recipient population with 900 individuals having allelic frequency of p and q is .30 and .70 respectively. If 100 migratory individual is inter from source to recipient population. After migration what is allelic frequency of p in their recipient population?
