AbstractIndividual multilocus heterozygosity estimates based on a limited number of loci are expected to correlate only weakly with the inbreeding level of an individual. Before using multilocus heterozygosity estimates in studies of inbreeding, their ability to capture information on inbreeding in the given setting should be tested.

AbstractInbreeding and genetic drift can decrease genetic heterozygosity, and this low heterozygosity can depress fitness, resulting in heterozygosity–fitness correlations (HFCs). HFCs are typically small in magnitude, a result often attributed to power of the analyses. Animal behaviors often affect fitness and are often heritable to some degree.

The variance of sample heterozygosity
Theoretical Population Biology, 1990The variance of sample heterozygosity, averaged over several loci, is studied in a variety of situations. The variance depends on the sampling implicit in the mating system as well as on that explicit in the loci scored and individuals sampled. There are also effects of allelic distributions over loci and of linkage or linkage disequilibrium between ...

Loss of heterozygosity by SCRaMbLEing
Science China Life Sciences, 2019Genetic variation drives phenotypic evolution within populations. Genetic variation can be divided into different forms according to the size of genomic changes. However, study of large-scale genomic variation such as structural variation and aneuploidy is still limited and mainly based on the static, predetermined feature of individual genomes.

TRANSLOCATION HETEROZYGOSITY, GENETIC HETEROZYGOSITY, AND INBREEDING INCLARKIA SPECIOSA
Evolution, 1977Numerous species have been found to have reciprocal translocations as a typical component of their genetic systems (Burnham, 1956). Theoretically, individuals which are heterozygous for reciprocal translocations could have greatly reduced genetic recombination compared to structural homozygotes, and it is commonly agreed this could have important ...

The most common molecular alteration observed in human cancers,1 loss of heterozygosity (LOH), is a significant mecha-nism by which critical genes involved in growth regulation and homeostasis become inactivated, or silenced, during disease evolution. This chapter provides a review of LOH and its implications in various cancers as well as a review of ...

Controlled heterozygosity in livestock
Proceedings of the Royal Society of London. Series B - Biological Sciences, 1955Abstract The word heterozygosity appears in the title of this paper in preference to heterosis for three reasons. First, heterosis has different usages and might be misleading. A simple illustration is provided by the colours of Shorthorn cattle which are determined by a pair of alleles.
