Question
If union of gametes to produce next generation is random, then the allele frequencies
between generations are ______________.
- Increasing
- Decreasing
- Constant
- Zero
Hint:
If union of gametes to produce next generation is random, then the allele frequencies
between generations are constant.
The correct answer is: Constant
- This conclusion is according to Hardy- Weinberg principle.
- If the union of gametes has been random in case of next generation production, therefore the frequency of the allele in the population are always constant.
- The expected frequencies are p2, 2pq, and q2
