Biology Question on Mechanism Of Evolution
Random genetic drift in a population probably results from
A
Highly genetically variable individuals
B
Interbreeding within this population
C
Constant low mutation rate
D
Large population size
Answer
Interbreeding within this population
Explanation
Solution
Genetic drift (Sewall Wright effect) is the random change in the frequency of alleles in a population over successive generations in the gametes. Each new generation differs from its parental generation with regard to allele frequencies simply because of random variation in the distribution of gametes. This process is more rapid in smaller populations, or when the alleles concerned confer no apparent benefit compared to their counterparts.
