The allele frequency represents the incidence of a gene variant in a population. Alleles are variant forms of a gene that are located at the same position, or genetic locus, on a chromosome.

The Hardy-Weinberg theorem characterizes the distributions of genotype frequencies in populations that are not evolving, and is thus the fundamental null model for population genetics. Under the ...

POD is an inflammatory facial eruption, presenting as tiny monomorphic flesh-colored to erythematous papules, vesicles, or pustules around the mouth (see Figure 1), and in some cases involving the ...

1 Homozygous for allele r rr Wrinkled 2 Homozygous for allele R RR Round Plants 2 and 3 both have the same phenotype even though they have different genotypes. This is because the effect of allele ...

Alleles can be dominant or recessive. Dominant alleles will be expressed even if a recessive allele is present. Recessive alleles will be overridden by the presence of a dominant allele.

Antitachycardia pacing (ATP) refers to the use of pacing stimulation techniques for termination of tachyarrhythmias. Such techniques can be automatically applied using implantable cardioverter ...
