Inbreeding depression may be reduced by selection against deleterious alleles, which eliminates, or purges, them from the population. I have two questions:
- Is genetic purging based on random shuffling of the genes of an individual or is it more intentional way of removing deleterious recessive alleles?
- Do the individuals/couple with deleterious alleles that breed together, pass down the purged genes EACH AND EVERY TIME they produce offspring? Does it happen every time they mate or just some times?
