How many of the following statements are correct for gene migration or gene flow:- (a) Gene frequencies change in the original population (b) Gene frequencies change in the new population (C) New gene/alleles are added to the new population (d) Genes are lost from the old population 1 Four 2 Three 3 Two 4 One

Fill up the balnks in the following paragraph by selecting the correct option. When migration of a section of population to another place and population occurs, I change in the original as well as in the new population new genes/ alleles are added to the ii, population and these are lost from the population. These would be a iv if this gene migration, happens multiple times. if the same change occurs by chance, it is called v. sometimes the change in allele frequency is so different in the new sample of population that they become a diffrent species. The original drifted population becomes founders and the effect is called vi

The frequency of a mutant gene in a population is expected to increase, if the gene is

Name the phenomenon that governs the following: A migrant beetle reproduces with the local population, as a result genes of migrant beetle enter the new population.

If change in gene frequencies in a population occurs by chance, than it is called as:

Presence of more than two alleles for a gene in a population is referred as

The phenomenon in which genes have two or more alleles that are common in a population is known as

In which condition gene pool/allelic frequency in population remains constant from generation to generation :-
