Natural selection in which more individuals acquire peripheral character value at both the ends of the distribution curve is
Stabilising natural selection
Disruptive natural selection
Directional natural selection
The curve never shows the formation of two peaks
Primary source of allelic variation is
Organic evolution would have not been taken place
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 ?
Definitions / Explanation : Genetic drift & Gene migration (gene flow)
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 ?
