To date, this wealth of germplasm is largely untapped owing to the difficulty of identifying agronomically important genes and transferring these genes into cultivated rice without any linkage drag or deleterious traits.

For 127 catastrophic Mendelian diseases (those caused by a single gene such as cystic fibrosis and ataxia-telangiectasia), there are presently 164 genes harboring 685 known recurrent variants that are highly penetrant and causal for deleterious traits, most typically manifesting in individuals before the age of 18 (18.

As is so often the case with human beings, for our minds seemed geared to create dichotomies, Simpson's categories were foreshadowed by Darwin's and Cuènot's initial recognition that preadaptations originated in two different ways: (1) a neutral or deleterious trait acquiring an adaptive function in a new environment and (2) a useful (adaptive) trait changing function.

Naturally, this might inadvertently increase the frequency of a linked deleterious trait, though the relatively high frequency of the 2 allele across many breeds argues that this is unlikely to present a major problem.

Trade-off theories are based on the assumption that reproductive aging is a deleterious trait that reduces individual fitness by reducing progeny production.
