A genotype tally for 100 individuals shows observed and HW-expected counts.
The deficit of heterozygotes and excess of homozygotes is most consistent with
- A
Strong heterozygote advantage
- Bcheck_circle
Inbreeding (non-random mating)
- C
High mutation rate
- D
Random mating
Explanation
Inbreeding causes a systematic excess of homozygotes (both AA and aa) at the expense of heterozygotes (Aa) - exactly the deviation pattern shown. Heterozygote advantage would do the opposite.
