Gene pool of a population tends to remain stable if the population is large, without large scale mutations, without migration and with

Gene pool of a population tends to remain stable if the population is large, without large scale mutations, without migration and with

According to modern synthetic theory of evolution proposed by Dobzhansky, all of the following are causes of genetic variability except (a) Gene mutations (b) Genetic recombination (c) Changes in chromosome number (d) Natural selection

Which of the following ways is most likely to decrease the genetic diversity in a population ? (a) Gene mutation (b) Genetic recombination (c) Stabilising natural selection (d) Immigration of individuals

Assertion : Hardy-Weinberg principle states that in the absence of disturbing influences, gene frequencies of large populations of sexually reproducing organisms do not change , provided that matings occur at random. Reason : The disturbing influences include mutation, gene flow, genetic drift, genetic recombination and natural selection.

[A]: According to Hardy-Weinburg law both gene frequencies and genotype frequencies will remain constant from generation to gen- eration in an infinitely large interbreeding population. [R]: Alleles segregating in a population tend to establish an equilibrium with reference to each other, thus maintain both frequencies constant.

Read the following statements and select the correct option. (i) Increase in metained months after industrialisation in Great Britain is a proof for natural selection. (ii) When more individuals of a population acquire a mean character value, it is called disruption. (iii) Changes in allelic frequency in a population will lead to Hardy-Weinberg equilibrium. (iv) Genetic drift changes the existing gene or allelic frequency in future generations.

Read the following statements and choose the correct option A. Increase in melanized moths after industrialization in Great Britain is a proof for natrual selection B. When more individuals of a population acquire a mean character value, it is called disruption C. Changes in allelic frequency in a population will lead to Hardly Weinberg equilibrium D. Genetic drift changes the existing gene ot allelic frequency in future generations

According to Hardy-Weinberg principle, allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences. It makes several assumptions which were given below. i. Random Mating ii. Sexual Reproduction iii. Non-overlapping Generations iv. Occurrence of Natural Selection v. Small size of population. Identify two assumptions which do not meet for a population to reach Hardy-Weinberg Equilibrium?
