allele

Homozygote (homozygous) --- An individual or genotype with identical alleles at a given locus on a pair of homologous chromosomes.

Furthermore, some characters were found to be associated with two or more polymorphic alleles, nearby in the same linkage group.

Genetic studies of cancer susceptibility have shown that most heritable risk cannot be explained by the main effects of common alleles.

All of these recessive mutations, which are considered to be null alleles, exhibit defects in internode elongation.

Allelic heterogeneity --- In a population, there may be a number of different mutant alleles at a single locus.

Regardless of the taxonomic status of these populations, adaptive alleles may have introgressed from archaic populations into modern humans.

Backcross breeding is a useful method to transfer favorable alleles from a donor parent into a recipient parent.

a person with a pair of dissimilar alleles is a heterozygote.

Mining useful alleles is one of the main activities in plant breeding.

People have two versions (known as alleles) of each gene, one from each parent.

Homozygous - When the two alleles of a gene on the two sets of chromosomes of an individual are identical.

In an individual, the same or similar phenotypes may be caused by different mutant alleles rather than by identical alleles at the locus.

Specific alleles at HLA loci are associated with diseases, often those suspected to be of autoimmune aetiology.

Moreover, population genetics studies suggest that some derived alleles that protect against common diseases became advantageous recently.

These different versions of each marker, called alleles, correspond to different versions of nearby genes.

There is an association between certain alleles and the clinical form of the disease.

RESULTS: The phenotype frequencies of HLA-DPB1 alleles of patients and control have no significant difference.

Linking SNP identities to the two HTT alleles, normal and disease-causing, is a prerequisite for allele-specific RNA interference.

Linkage disequilibrium (LD)-based association analysis is an effective approach to find new genes and favorable alleles.

Mendel'swork found that alleles assort independently in the production ofgametes, or germ cells, ensuring variation in the next generation.

Brothers of gay men who have only some of the alleles would turn out straight but less aggressive than typical guys.

Alleles at both loci need to be the same for an incompatible reaction.

Objective To present a rapid, sensitive and safe procedure for the determination of human apolipoprotein E alleles.

Methods: designing cynomolgus monkey MHC-I B allele specific primers, amplified by PCR to obtain full-length alleles.

The number of S alleles is similar to that in gametophytic systems but some have a dominance hierarchy.

These events involve somatic mutations as well as inherited alleles.

Classical genetic studies show that gene conversion can favour some alleles over others.

Unique and deficient alleles in each geographic population were detected.

An organism thAT has the same alleles AT a particular gene locus on homologous chromosomes.

Risk from both alleles was confined to estrogen receptor-positive tumors.

Conclusions: A genetic susceptibility to both type 1 diabetes and celiac disease shares common alleles.

The objectively genetic relationships of Chinese soybean cultivars could be reflected using over 570 alleles. 2.

Tissue Factor and Platelet Glycoprotein IB-alpha Alleles Are Associated with Age at First Coronary Bypass Operation Donahue BS, et al.

The recognition is controlled by one locus with many 'S' alleles.

The same locus showed the different level of genetic diversity and alleles in different population.

Results: The mutation of the new alleles of 2 pedigrees was increasing and decreasing a single repeat.

They are encoded in genetic material, usually DNA, and some come in different versions, called "alleles. "

In addition, the epigenetic state determines whether these alleles are dominant.

No apparent change for frequencies of the 12 different alleles was found in the 9-month longitudinal study.

Alleles C of position -69 possibly play a role in preventing tuberculosis.

This system involves one gene locus with many alleles (i. e. different forms of the one gene), probably 20-50 in most species.

For most genes, both the maternal and paternal alleles turn on or off at the same time. Imprinting disrupts this balance.

Currently the database covers 52 diseases with information on 5760 individuals carrying the mutant alleles of causal genes.

Certain HLA class I alleles are markedly enriched in elite controllers, with the highest association observed for HLA-B57 (ref. 1).

Only the limited DNA samples were available and we could not amplify the repeat region from 155 alleles.

Resistant alleles at both gene loci were derived from Gumei 2, indicating an existence of resistance gene clusters in Gumei 2.

the rest loci of the alleles number were between 7 and 11.

There are some mammalian alleles that display the unusual characteristic of variable expressivity in the absence of genetic heterogeneity.

According to the sequence detected by us, we found that two alleles consisted in BMI, and named them as EBMI and Ebmi.

Having different alleles at one or more corresponding chromosomal loci.

The average heterozygosity and effective number of alleles among 15 populations were 0. 2746 and 1. 559 respectively.

The heterozygosity, number of effective alleles, and polymorphism information content were 0. 3711, 1. 5901, 0. 3022, respectively.
