a pattern of inheritance in which the transmission of traits depends on the presence or absence of certain alleles on the autosomes. The pattern may be dominant or recessive, and males and females are usually affected with equal frequency. The majority of hereditary disorders are the result of a defective gene on an autosome. Kinds of autosomal inheritance are autosomal-dominant inheritance and autosomal-recessive inheritance. See also inheritance.
autosomal inheritancea pattern of transmission of ALLELES that are located on AUTOSOMES, i.e. not on sex chromosomes, so that the sex of the parent does not affect the result of a mating, RECIPROCAL CROSSES giving identical results.
1. the acquisition of characters or qualities by transmission from parent to offspring.
2. that which is transmitted from parent to offspring. See also gene, deoxyribonucleic acid and heredity.
Mendelian inheritance is the basis of all genetic practice, but it has limitations in explaining the small differences that occur in a range of offspring of similar and related matings. Galtonian genetics deals specifically with this problem and is better fitted as a tool in population genetics and in dealing with characters that are dependent on a number of chromosomal loci rather than on a single locus.
controlled by genes located on autosomes.
inheritance in which the phenotype of the heterozygote falls between that of either homozygote.
the transmission of characters that are dependent on peculiarities of the egg cytoplasm produced, in turn, by nuclear genes.
