The conflict between inbreeding and selection I. Sele fertilization
Tóm tắt
Reason is given for doubting the validity of Hayman & Mather’s results on this question. Selection in favour of heterozygotes within lines slows down the onset of homozygosis, but cannot prevent it, if any homozygotes are allowed to breed. Similar selection between lines leads to different equilibria in different circumstances.
