Results for heterozygote

Evolution A-Z Heterozygote / homozygote.
Heterozygote / homozygote. A heterozygote is an individual having two different alleles at a genetic locus; a homozygote is an individual having two copies of the same allele at a locus. The term homozygote is also sometimes applied to larger genetic entities, such as a whole chromosome: a homozygote is then an individual having two copies of the same chromosome.
Heterozygote Definition of Heterozygote at
But in a heterozygote potency is usually more or less reduced. Inheritance of Characteristics in Domestic Fowl Charles Benedict Davenport. Some are probably matings of two heterozygote s, others of two recessives, and others still of a recessive with a heterozygote.
Heterozygote advantage as a natural consequence of adaptation in diploids PNAS.
For heterozygote advantage to be consequential i.e, to be capable of effectively stabilizing a balanced polymorphism against the stochastic fluctuations arising from random genetic drift, the fitness advantages of a heterozygote over its two homozygote have to be at least of order 1/ N 10.
Heterozygote biology Britannica.
a hybrid plant, termed a heterozygote R r. Since the gene R, for purple, is dominant over r, for white, the F 1 generation hybrids will show purple flowers. They are phenotypically purple, but their genotype contains both R and r genes, and these alternative allelic or allelomorphic genes do not blend.

However, alleles are not always dominant one over another; and often there are more than two alleles at a given locus, especially in polyploids. Because it has two or more different alleles at a given locus, a heterozygote does not breed true.
Heterozygote advantage Wikipedia.
The heterozygote expressed none of the disadvantages of homozygotes, yet gained improved viability. The homozygote wild type was perfectly healthy, but did not possess the improved viability of the heterozygote, and was thus at a disadvantage compared to the heterozygote in survival and reproduction.
Heterozygote Advantage for Fecundity.
Second, the heterozygote advantage arises because of the super-position of two opposite directional selection pressures malaria and sickle-cell anaemia, so it is not really a true case of heterozygote advantage arising from the heterozygote having superior fitness for a specific trait.
Definition of Heterozygote.
Heterozygote: An individual who has two different forms of a particular gene, one inherited from each parent. A heterozygote for cystic fibrosis CF has the CF gene on one chromosome 7 and the normal paired gene on the other chromosome 7.
How general is heterozygote superiority?
University of Veterinary Medicine, Vienna. Heterozygote superiority is rare see Hedrick 2012 Trends Ecol Evol 2712: 698-704, and many examples that are assumed to be heterozygote superiority, such as MHC loci, can be explained by heterozygote advantage through dominance Penn et al.
