genotype

[jē′nōtīp′]

Etymology: Gk, genos, birth, typos, mark

1 the complete genetic constitution of an organism or group, as determined by the specific combination and location of the genes on the chromosomes.

2 the alleles situated at one or more sites on homologous chromosomes. A pair of alleles is usually designated by letters or symbols, such as AA when the alleles are identical and Aa when they are different.

3 a group or class of organisms having the same genetic makeup; the type species of a genus. Compare phenotype. genotypic, adj.

genotype

The complete genetic constitution of an individual at a particular location (locus) in the genome. At many locations (loci) throughout the genome, the chromosomal DNA sequence differs subtly between individuals. Each of the various DNA sequences at one locus is called an allele: for instance, if there are three sequence variants present, then there are three alleles. Offspring inherit one homologous chromosome from each parent. Thus, a genotype comprises two alleles: the allele inherited from the father (carried on the paternal chromosome) and the allele inherited from the mother (carried on the maternal chromosome). See gene; phenotype.
