Important Questions on Evidences of Evolution
The wing of a cockroach and the wing of a bird represent which of the following organs.
According to Hardy-Weinberg’s principle, if allele one is denoted as ‘A’ and allele two as ‘a’ and their frequencies are denoted by p and q, and if random mating occurs. The frequency of heterozygous individual would be:
The family tree of Lemurs split off from the Last Common Primate Ancestor (LCPA) as 'wet-nosed monkeys', while the other branch of 'dry-nosed monkeys' eventually gave rise to the human lineage. Thus, Lemurs are ancient evolutionary cousins of humans. While humans entirely depend on vitamin as a dietary supplement (citrus fruits), Lemurs can synthesize their own. This is an example of divergent evolution wherein Lemurs have retained gene , one of those responsible for vitamin biosynthesis. The option that best satisfies this information is

Statement I : Homologous organs exhibit convergent evolution.
Statement II : Analogous organs exhibit divergent evolution.
The correct option among the following is
