Important Questions on Hardy Weinberg's Principle
If the high altitude birds become rare or extinct, the plants which may disappear along with them are
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 pattern of natural selection that converts a unimodal distribution of a given phenotype into a bimodal is:
During industrial revolution, killing off which organism that grows on the trees turned the tree trunks black?
In a diploid population at Hardy-Weinberg equilibrium, consider a locus with two alleles. The frequencies of these two alleles are denoted by and respectively. Heterozygosity in this population is maximum at:
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

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:
