genetic load

genetic load
(= genetic burden)
In general terms the decrease in fitness of a population (as a result of selection acting on phenotypes) due to deleterious mutations in the population gene pool. More specifically, the average number of recessive lethal mutations, in the heterozygous state, estimated to be present in the genome of an individual in a population.
