The white color and the mode of inheritance are controlled by an autosomal dominant allele designated I (KIT) for 'inhibition of color' (Ollivier and Sellier, 1982).
Although the recessive allele (a) in the A locus can lead to black genotyped sheep, the dominant allele ([E.
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.
Population genetics statistics of polymorphism sites in LPL gene from different goats: Population genetics analysis showed that five genotypes were detected in 6 goat populations in the P1 site, in which BB genotype is homozygous dominant, allele B is the dominant allele (Table 2).
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.
Homozygous locus is indistinguishable from a heterozygous one when a dominant allele is involved.

With our new mathematical concept, biology students can better understand that, in the case of heterozygous traits, a dominant allele determines appearance by contributing 100% to the overall phenotype, whereas the recessive allele has no observable effects on the organism and, hence, contributes 0%.
If one parent passes on the dominant allele for a particular trait, and the other parent passes on a recessive allele, the child's genotype will be mixed, one dominant and one recessive, but the phenotype will be that of the dominant allele.
