A population will not exist in Hardy Weinberg equilibrium if :
1 There are no mutations
2 There is no migration
3 The population is large
4 Individuals mate selectively
Explanation:
A population will not exist in HardyWeinberg equilibrium if individuals mate selectively. Hardy-Weinberg equilibrium assumes random mating, meaning individuals mate without preference for specific traits. This ensures that allele frequencies remain constant over generations. If selecting mating occurs, it can lead to changes in allele frequencies violating the equilibrium assumption.
1 Stabilizing selection as it stabilizes this character in the population
2 Directional as it pushes the mean of the character in one direction
3 Disruptive as it splits the population into two one yielding higher output and the other lower output
4 Stabilizing followed by disruptive as it stabilizes the population to produce higher yielding cows
Explanation:
The directional stabilization occurs when one genotype with desired characters of an individual is favored in a population. In case of artificial selection, high yielding milking cow are preferred. When middle trait is selected, i.e. cow with intermediate yielding capacity then the selection is termed as stabilizing. When the two extreme traits are selected, i.e. cow with high and low yields respectively then the selection is termed as disruptive.

Which one of the following is a wrong statement regarding mutations
1 UV and Gamma rays are mutagens
2 Change in a single base pair of DNA does not cause mutation
3 Deletion and insertion of base pairs cause frame-shift mutations
4 Cancer cells commonly show chromosomal aberrations
Explanation:
Change in a single base pair of DNA cause mutation which are called point mutation. Point mutation is a change in a single nitrogenous base. An example of point mutation is sickle cell anemia. It involves mutation in a single base pair in the betaglobin chain of hemoglobin pigment of the blood.

In which condition, the gene ratio remains constant for any species
1 Sexual selection
2 Random mating
3 Mutation
4 Gene flow
Explanation:
According to Hardy-Weinberg law, "In a large random - mating population that is not affected by the evolutionary processes of mutation, migration or selection, both the allele frequencies and the genotype frequencies are constant from generation to generation.

2 Gene flow
3 Genetic Drift
4 Isolation
Explanation:
Genetic Drift is also called Sewall Wright Effect. Genetic drift is change in the frequency of an existing within a population over chance. The phenomena of genetic drift was explained by Sewall Wright.
