Two populations of the same species are separated by a mountain range. Population A has q = 0.3 and population B has q = 0.7 for the same gene. After the mountain range is removed and populations merge, what is the expected combined q (assuming equal population sizes)?

The Miller-Urey experiment established that:

Assertion (A): Hardy-Weinberg equilibrium is maintained even when natural selection favours the heterozygote. Reason (R): Heterozygote advantage is a form of balancing selection that maintains allele frequencies.

Assertion (A): Wings of bat and wings of eagle are homologous organs. Reason (R): Both bat and eagle wings are modifications of the tetrapod forelimb and have the same embryonic origin.

A gene has two alleles, B (frequency p = 0.6) and b (frequency q = 0.4). Natural selection reduces the fitness of bb individuals by 10% (selection coefficient s = 0.1). In the NEXT generation, the frequency of b will:
