The effect of structural aberrations of the chromosomes on reproductive fitness in man. I. Methodology

The effect of structural aberrations of the chromosomes on reproductive fitness in man. I. Methodology

N E Morton et al. Clin Genet. 1975 Sep.

Abstract

Methods are presented to estimate relative fitness of carriers as a function of fertility, survival, are generation time in pedigrees under incomplete ascertainment. A large sample of diverse chromosomal aberrations reveals significant effects on all three parameters, giving a relative fitness of .769 +/- .039. There is no significant shift in segregation frequency. Implications of these results for population dynamics of structural rearrangements are discussed. The following paper applies these methods to specific classes of aberrations.
