In a population of 1000 individuals, 360 belong to genotype AA, 480 to Aa and the remaining 160 to aa. Based on this data, the frequency of allele A in the population is:
1. | 0.4 | 2. | 0.5 |
3. | 0.6 | 4. | 0.7 |
List-I | List-II | ||
A. | Gene pool | I. | Stable within a generation |
B. | Genetic drift | II. | Change in gene frequency by chance |
C. | Genetic flow | III. | Transfer of genes into or out of population |
D. | Gene frequency | IV. | Total number of genes and their alleles |
Variation in gene frequencies within populations can occur by chance rather than by natural selection.
This is referred to as:
1. Genetic drift
2. Random mating
3. Genetic load
4. Genetic flow
In Hardy-Weinberg equation, the frequency of heterozygous individual is represented by?
1. | p2 | 2. | 2pq |
3. | pq | 4. | q2 |
Assertion (A): | Deviation from Hardy-Weinberg equilibrium is evidence of evolutionary change within a population. |
Reason (R): | Genetic drift, gene flow, mutation, non-random mating, or natural selection can lead to deviation from Hardy-Weinberg equilibrium. |
1. | Both (A) and (R) are True and (R) is the correct explanation of (A) |
2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
3. | (A) is True but (R) is False. |
4. | (A) is False but (R) is True. |
