This event is called “loss of heterozygosity” and is not inherited. ❋ Unknown (2010)
There is also an unusual phenomenon called loss of heterozygosity (LOH) whichis described below. ❋ Unknown (2010)
Outbreeding groups of organisms with high degrees of heterozygosity tend to be fitter than inbred groups. ❋ Unknown (2010)
Sickle cell anemia is caused by having two copies of the sickle cell allele and is a necessary by-product of strong selection for heterozygosity in malaria-ridden regions. ❋ Unknown (2009)
So, in order for this model to apply to homosexuality you'd have to show that there's some sort of massive fitness benefit on the level of sickle heterozygosity that causes homosexuality to persist at levels 1%, which more than makes up for the fitness costs of preferential homosexuality. ❋ Unknown (2009)
Since the alleles have no effect on fitness, a very large number of allelic variants can be in the population and not reduce its fitness, thus solving the heterozygosity problem. ❋ Unknown (2007)
I would be interested to see a more in-depth explanation of “lethal” heterozygosity levels and the various ways later researchers were able to account for them. ❋ Unknown (2007)
Kimura Kimura, 1968 used the heterozygosity problem to advance the neutral theory. ❋ Unknown (2007)
The authors concluded that heterozygosity explained only a very small amount of variation in symmetry. ❋ Field Notes (2006)
One important effect of random drift is to decrease the degree of heterozygosity in a population over time. ❋ Okasha, Samir (2006)
Two measures of genetic diversity were possible using electrophoresis: (1) the number of loci polymorphic; and, (2) the average heterozygosity per an individual. ❋ Wade, Michael (2005)
Soulé mentioned eighteen factors, any or all of which might contribute toward a given extinction: 1. Rarity (low density) 2. Rarity (small, infrequent patches) 3. Limited dispersal ability 4. Inbreeding 5. Loss of heterozygosity 6. Founder effects 7. Hybridization 8. Successional loss of habitat 9. Environmental variation ❋ David Quammen (2004)
Back in the lab, the freshened Stephie tries to engage Gus in a deep conversation about the loss of heterozygosity or some other such nonsense. ❋ Unknown (2004)
Even disease carriers have a valuable contribution to make in preserving heterozygosity: a dog that carries an epilepsy gene, for example, could also very well carry a gene that protects against cancer. ❋ Unknown (1999)
The self-fertile species should have less heterozygosity and consequently should retain fewer of the deleterious recessives. ❋ Unknown (1989)
Moreover, the same proves to be true of any point of discontinuity in pairing, caused by heterozygosity in regard to a structural change. ❋ Unknown (1964)
Van Driest SL, Vasile VC, Ommen SR, Will ML, Tajik AJ, et al. (2004) Myosin binding protein C mutations and compound heterozygosity in hypertrophic cardiomyopathy. ❋ Jennifer Davis Et Al. (2010)
There was little [correlation] between current levels of [inbreeding] or [reduced] heterozygosity and prevalence of genetic disease. ❋ K8lynIg (2020)
