Variation in gene frequencies within populations can occur by chance rather than by natural selection. This is referred to as 1. Random mating 2. Genetic load 3. Genetic flow 4. Genetic drift

Frequency of a gene in a population will increase if the gene is

Gene flow occurs through generations. Gene flow can occur across language barriers in humans. If we have a technique of measuring specific allele frequencies in different population of the world, can we not predict human migratory patterns in pre-history and history ? Do you agree of disagree ? Provide explanation to your answer.

[A]: According to Hardy-Weinburg law both gene frequencies and genotype frequencies will remain constant from generation to generation 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.

A gene which can occur is more than two alternative forms present on the same locus is called

The spread of genes from one breedign population to another by migration which may result in changes in gene frequency is called

Read the following statements amd select the correct option .A . increase in the melanised moths after industrialisation in Great Britain is proof of natural selection. B. When more individuals of a population acquire a mean character value ,it is called disrupation . C . Changes in allelic frequencey in a population will lead to Harry -Weingberg equilibrium. D. Genetic drift changes the existing gene allelic frequency in future generations.

Let us consider 1 mol of gas. If It Is an ideal gas then (Poverset-V)/(RT) = 1 where , overset-V = molar volume of a gas For a non-ideal gas this quotient may not be equal to 1. It can also be less than or greater than 1. Therefore, the above quotient is defined as compressibility factor Z. Z = (Poverset-V)/(RT) = (Molar volume of real gas)/ (Molar volume of ideal gas) The compressibility factor of real gases can be written as Z = (Poverset-V)/(RT)=1+B/overset-V+C/overset-(v^2)+D/overset-(v^3)......(Viral equation) Where B,C,D are called virial coefficients and are dependent on the nature of the gas and temperature. B=(b-a/(RT)) .At Boyle’s temperature,second virial coefficient becomes zero. when Zgt1 repulsive forces are dominant and when Zlt1 the forces of attraction are dominant.
