Directional evolution
Disruptive evolution
Molecular evolution
All of these
State and explain any three factors affecting allele frequency in populations.
Factor affecting the Hardy-Weinberg principlesare
$(I)$ Gene flow ;
$(II)$ Genetic drift
$(III)$ Mutation
$(IV)$ Genetic recombination
$(V)$ Natural selection
The correct combination is
What is founder effect ?
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 ?
Natural selection where more individuals acquire specific character value other than the mean character value, leads to:
