Hardy Weinberg's Principle

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?

In a diploid population at Hardy-Weinberg equilibrium, consider a locus with two alleles. The frequencies of these two alleles are denoted by $\mathrm{p}$ and $\mathrm{q},$ respectively. Heterozygosity in this population is maximum at:

Which of the following statement is true about the founder effect?

The single-step large mutation that leads to speciation is called saltation or migration?

The peppered moths are found in two distinct forms. One form is dark-coloured and the other is light-coloured. The moths rest on the tree trunks. The light-coloured tree-trunks in an area were darkened by pollution. What would happen to the numbers of the two forms of the peppered moths in that area?

Natural selection operates on the _____ of an individual organism.

The bill sizes in a bird species of seed crackers from West Africa shows a bimodal distribution. Their most abundant food sources are two types of marsh plants that produce hard and soft seeds, consumed preferentially by the large and small billed birds, respectively. This bimodal distribution of bill sizes is a likely consequence of

In a population, $N_{AA}$ and $N_{aa}$ are the numbers of homozygous individuals of allele '$A$' and '$a$', respectively and $N_{Aa}$ is the number of heterozygous individuals. Which one of the following options is the allele frequency of '$A$' and '$a$' in a population with $N_{AA}=90, N_{Aa}=40$ and $N_{aa}=70?$

Assertion (A) : Geographical isolation brings about the sympatric speciation

Reason (R): If one species diverges to become two or more species, it is called cladogenesis

Study the following statements and identify the incorrect statement regarding genetic drift

In a population of 1000 individuals, 28% are homozygous dominant, 48% are heterozygous dominant, and the remaining are recessive. Find out the dominant allelic frequency.

Which of the following schematic diagram best explains showing phenotypic distribution explains the "directional selection" due to natural selection:

If a gene has four alleles, number of expected genotypes is

In Hardy Weinberg population $2 \mathrm{pq}$ represents:

Define the following term:

Speciation

_____ drift is most effective in small populations of organisms.

Which type of selection is a suitable example for industrial melanism? (Directional selection/Disruptive selection/ Facultative Selection)

Explain the terms: Gene pool and Gene frequency.
