Answer to Question #41316 in Other Biology for qwerty
The existence within a population of nonbeneficial allele in heterozygous genotype is :- (1) genetic drift (2) genetic flow (3) selection (4) genetic load
The concept of genetic load comes from Haldane (1949) and Muller (1950). It attempts to put some objectivity into the idea that populations have a mixture of genotypes, some of which are 'better' than others. To the extent that there is a 'best' genotype, any genotypes other than the best will be part of the genetic load in the population. Thus, the correct answer is 4
