Related to Mutational load: Genetic burden
the aggregate of more or less harmful genes that are carried, mostly hidden, in the genome that may be transmitted to descendants and cause morbidity and disease; in classic genetic dynamics, genetic load may be seen as undischarged genetic debts that result from previous mutations, each of which is supposed to exact an average number of lethal equivalents dependent only on the pattern of inheritance, regardless of how mild or severe the phenotype may be.
