A gene locus has two alleles A, a. If the frequency of dominant allele A is 0.4, then what will be the frequency of homozygous dominant, heterozygous and homozygous recessive individuals in the population?
| 1. | 0.16 (AA); 0.36 (Aa); 0.48 (aa) |
| 2. | 0.36 (AA); 0.48 (Aa); 0.16 (aa) |
| 3. | 0.16 (AA); 0.24 (Aa); 0.36 (aa) |
| 4. | 0.16 (AA); 0.48 (Aa); 0.36 (aa) |
Genetic drift operates in:
1. small isolated population
2. large isolated population
3. non-reproductive population
4. slow reproductive population
In Hardy-Weinberg equation, the frequency of heterozygous individual is represented by?
1. p2
2. 2pq
3. pq
4. q2
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
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
