Question

6. True (a) or False (b), inbreeding promotes genetife Multiple Choice genetic variation within that o a population tends to population. e)invert d) standardize a) increase b) not change c) reduce . The probability that two alleles are identical by descent is the 8· a) coalescent b) inbreeding coefficient c) panmictic constant d) outcrossing rate e) negative assortative rate 9. Rapid fixation of alleles bytake place in populations that are small. a) mutation b) evolving c) inbreeding d) random migration genetic drift 10. Which of the following is NOT an evolutionary force that changes allele a) mutation b) selection c) migration infinitely large population

Explanation / Answer

7. Answer will be a. There are many factors which are responsible for changes in allele frequency , migration also called gene flow is one of them .

8. Answer will be b.if there are identical allele in a closed population ,it will possible only due to inbreeding.

9. Answer will be d. Fixation is the stability of a particular allele till mutation or gene flow. In a small population genetic drift play a major role to achieve the fixation of allele .

10. Answer will be d. Mutation is the change in dna resulting in changes in allele frequency which are responsible for evolution, selection also changes the allele frequency if nature select a particular allele for reproduction then only their frequency is remain , migration also affect the allele frequency by decreasing or increasing it whearease large infinite population has no effect on evolution if there is no external factor.
