Vertebrates are typically diploid (two DNA copies), but plants are often polyploid (more than two copies of DNA). If a population of humans were to inbreed for a few generations, the children could end up with double copies of a lot of recessive genes. WebDarwin (1876) also reported that inbreeding in plants results in deterioration of vigour and the crossing in hybrid vigour. On the basis of his experiments Beal (1877-1882) concluded that F 1 hybrids yield as much as 40 percent more of the parental varieties..
