genotype

(jĕn′ə-tīp′, jē′nə-)
n.
1. The genetic makeup, as distinguished from the physical appearance, of an organism or a group of organisms.
2. The combination of alleles located on homologous chromosomes that determines a specific characteristic or trait.
3. A specific combination of alleles at one or more loci on a chromosome.

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

Genetics The entire genetic makeup of an organism, the type species of a genus, defined by the complement of allelic forms of each gene or genetic markers present in an organism's genome. See Gene, Genetic marker, Nucleus, Phenotype.

gen·o·type

(jē'nō-tīp)
1. The genetic constitution of an individual.
2. Gene combination at one specific locus or any specified combination of loci.
[G. genos, birth, descent, + typos, type]

genotype

1. The total genetic information contained in a cell.
2. The genetic constitution of an individual organism. Compare PHENOTYPE.

genotype

the genetic constitution of an individual, usually referring to specific CHARACTERS under consideration. Thus, the two alleles of the human albino gene can be written A and a , with three possible genotypes: a/a, A/a and A/A. See DOMINANCE (1) for the expression of the genotype in the PHENOTYPE.

genotype (jēˑ·nō·tīp),

n an organism's genetic makeup.

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.

The existence of heritable variations (individual differences that can be traced to a dunamis in the organism's formal nature) thus suggests that being the intrinsic object of a dunamis is not sufficient for teleology.
To examine heritable variation in the traits, regressions of mean offspring phenotypic values on female parent values were performed, based on data from 99 (Cairns), 178 (Gold Coast), and 124 (Cherry Hill) families.

However, values of "explained" heritable variation (VQTL) were generally higher in the MN than in the MA or NA populations.

In summary, the QTL linked to Satt277 accounts for 16% of the heritable variation in yield, is operational in different environments, is conditional in all environments on a QTL linked to B172_2, and may either be independent of maturity or have a preferential effect on early maturing plants as in Minnesota 1996.
For herbivore species to act singly as selective agents on plant resistance traits, there must be heritable variation in resistance to individual herbivore species (Falconer 1989).
By contrast, most previous studies of the mechanisms that maintain heritable variation in populations have examined traits (including allozymes and DNA sequences) whose relationship to organismal performance is uncertain and difficult to establish.
3) Is there heritable variation for phenological characters or genetic correlations between characters that could act as evolutionary constraints?
The model in this paper has a very specific assumption about good genes: the heritable variation in fitness is maintained by deleterious mutation occurring throughout the genome.
