Answer 1

Question 13

Answer: Genetic divergence occurs due to accumulation of genetic changes or mutation in two or more populations of ancestor species after the population become reproductively isolated. It is the basic mechanism responsible for speciation (formation of new species). Hence, the correct answer option b. It does not involves new variation, new alleles, new competition and new gene frequencies. So, options a, c, d, e are incorrect.

Question 14

Answer: An allele is dominant if its effect mask that of a recessive allele paired with it. This is called as complete dominance. Hence, the option A is the correct answer and option B is incorrect answer. In codominant condition, neither allele mask the effect of another allele. hence option c, d and e are incorrect.
