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:
Darwin’s finches illustrate which of the following phenomenon:
Reproductive barriers are mechanisms which help maintain species over time. Three examples of reproductive barriers in certain species are given below:
A. Two species of garter snakes occur in the same area but one lives in water while the other is terrestrial.
B. Some salamander sub-species of genus Ensatina live in the same region and occasionally hybridise resulting in frail individuals in the next generation.
C. Blue-footed boobies (a type of bird) mate only after a courtship display wherein the male draws the female's attention to its bright blue feet.
Indicate whether these are examples of pre-zygotic or post-zygotic or post-zygotic reproductive barriers.
In a large, randomly mating population, only one person in 10,000 is an albino. What will be the frequency of a carrier person of albinism?
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
The condition(s) that allow(s) a population to exist in genetic equilibrium is/are:
What is taxonomy characteristics and evolutionary history?
Does taxonomy show evolutionary relationships?
As evidence from records which era had no life
Which era is known as the age of early unicellular life?
