Multiple choice question.

In Hardy - Weinberg equation, the frequency of homozygous recessive individual is represented by:


How does Hardy-Weinberg’s expression (p2+2pq+q2=1) explain that genetic equilibrium is maintained in a population? List any four factors that can disturb the genetic equilibrium.


Explain how mutations, natural selection and genetic drift affect Hardy Weinberg equilibrium.


Hardy - Weinberg equilibrium is known to be affected by gene - flow, genetic drift, mutation, genetic recombination and


The factor that leads to the Founder effect in a population is ______


In a certain population, the frequency of three genotypes is as follows:

Genotypes:  BB  Bb  bb
frequency: 22% 62%  16%

What is the likely frequency of B and b alleles?


Among the five factors that are known to affect Hardy-Weinberg equilibrium, three factors are gene flow, genetic drift and genetic recombination. What are the other two factors?


Gene flow occurs through generations. and 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 or disagree? Provide explanation to your answer.


Name the law that states that the sum of allelic frequencies in a population remains constant. What are the five factors that influence these values?


How is Hardy-Weinberg’s expression “(p2 + 2pq + q2) = 1” derived?


List any two factors that can disturb the genetic equilibrium.


Explain Hardy-Weinberg's principle


Write Hardy Weinberg's equation.


The black colour on the beak of finches dominates over the yellow colour. There are 210 individuals with the genotype DD, 245 individuals with the genotype Dd and 45 individuals with the genotype dd. Deduce the frequency of individuals with dominant, heterozygous, and recessive traits.


What does the Hardy-Weinberg equation \[p^2 + 2pq + q^2 = 1\] represent?


Where do a large proportion of recessive alleles exist in a population at Hardy-Weinberg equilibrium?


What does genetic drift cause in a population, particularly in new samples of a population?


Why are alleles present in homozygous recessive organisms exposed to environmental selection?


What does it indicate when the measured frequency of an allele differs from the expected Hardy-Weinberg value?
