genetic load
genetic loadn.1. The relative difference between the theoretically most fit genotype within a population and the average genotype.2. The aggregate of deleterious genes that are carried, mostly hidden, in the genomes of a population and may be transmitted to descendants.genet′ic load′
n. the extent to which a population deviates from the theoretically fittest genetic constitution. [1965–70] genetic load
genetic load[jə¦ned·ik ′lōd] (genetics) The reduction in fitness of a diploid population due to new mutant genes and those already in the gene pool. genetic load
ge·net·ic loadthe 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.genetic loadn.1. The relative difference between the theoretically most fit genotype within a population and the average genotype.2. The aggregate of deleterious genes that are carried, mostly hidden, in the genomes of a population and may be transmitted to descendants.ge·net·ic load (jĕ-net'ik lōd) The aggregate of more or less harmful genes that are carried, mostly hidden, in the genome and may be transmitted to descendants and cause disease. genetic load The totality of abnormalities caused in each generation by defective genetic material carried in the human gene pool.genetic load a measurement of the amount of deleterious genes in a population, calculated as the average number of lethal equivalents per individual. |
