We also hypothized that the predominant red coat color is produced by homozygous e/e alleles, and black coat color results from dominant allele [E.sup.D], while wild type allele [E.sup.+] might produced the miscellaneous coat colors in Mongolian goat populations.
At the T516121C locus, the AB genotype was the predominant genotype, and allele B was the dominant allele. In the C504498T locus, the CD genotype was the predominant genotype, and allele C was the dominant allele.
In black goat and Yaoshan goat, G is the dominant allele in G447C.
In the exploratory analysis, the dominant allele model revealed total MET minutes per week (ES = 0.22, P = 0.03, Supplementary Table 2) and a tendency for vigorous MET minutes per week (ES = 0.19, P = 0.08) to be higher in A allele carriers (AA/AT) than nonrisk allele carriers (TT).
Taken together, it may be hypothesized that the +49 G allele acts as a dominant allele in relation to decreasing the risk of recurrent spontaneous abortion among Iranian women of southwest.
She isn't yellow, so she must have a dominant allele at one of the E loci.
When there is Hardy-Weinberg Disequilibrium the marker alleles and haplotypes are not independent of each other so the effects of disease predisposing alleles and haplotypes may be 'masked' by other non-disease predisposing alleles and haplotypes [25] or, in the case of a recessive condition, by the presence of a dominant allele on the homologous chromosome.
Adalsteinsson [29] also suggested that the variation in the spotted (SS) effect can be explained by the action of modifiers, and white head spot occurs in animal heterozygous for white markings by incomplete dominance of the dominant allele (S+) for full pigmentation.
According to this model, vernalization response in barley is mainly determined by VRN-H1 locus on chromosome 5H and VRN-H2 locus on chromosome 4H, where genotypes with dominant allele Vrn-H2 on VRN-H2 locus and recessive allele vrn-H1 on VRN-H1 locus require the greatest vernalization requirement.
Homozygous locus is indistinguishable from a heterozygous one when a dominant allele is involved.
All KRAS mutant-positive adenomas and 16 of 18 carcinomas harbored a dominant allele. In contrast, the proportion of adenoma cases having multiple mutant alleles was 21% (3 of 14) for adenomas and 7% (2 of 27) for the carcinomas (Fig.
