FSC Part 2 Biology Chapter 24 Short Questions Notes – Evolution
What is the application of Hardy-Weingberg therorem?
The Hardy-Weinberg equation is used for calculating the frequencies of alleles and genotypes in populations at equilibrium.
Define Mutation. What is its role in change of genotypic frequency?
A spontaneous change in part of DNA is called mutation. Mutation is the ultimate source of all changes. But individual mutations occur bery rarely. Thus mutation alone does not change allele frequency much.
Define migration. What is its role in change of genotypic frequency?
The movement of an organism form one population to the other is called migration. It is also a very poetential agent of change. Migration prevents the populations from exchanging the diverging characters within its members.
What is an endagered species? How is it different from threatrened species?
An endangere species is in imminent danger of extinction throughout its range. A threatened species is likely to become endangered in the near future.
State Hardy-Weinberg theorem.
It states that the frequencies of alleles and genotypes in a population’s gene pool remain constant over the generation unless acted upon by agents other than sexual recmbination.
