Which one of the following factor do not allows Hardy-Weinberg principle to operate?
Inbreeding
Mutation
No selection
No migration
Primary source of allelic variation 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 ?
Write short note on Hardy - Weinberg principle.
Variation in gene frequencies within populations can occur by chance rather than by natural selection. This is referred to as
Give scientific reasons : Genetic drift is much more likely to change allele frequencies in a small population rather than large population.
