Sentence examples for mating modifier allele from inspiring English sources

In a homotypic encounter for the mutant mating modifier allele A1 it is assumed that the probability of fusion of the gametes is the same for the two homotypic associations at the object locus B, i.e. This is a reasonable assumption in view of the fact that changes in genetic coherence show primarily in alterations of the fusion probabilities for heterotypic combinations at the object locus.

With mating modifiers present in the population, complete conditional overdominance at the B-locus is required for a stable polymorphism, and this is equivalent to.

This is in fact the situation of the absence of any genetic coherence, and it will be assumed to be realized for the wild type allele A2 at the mating modifier locus.

It is shown that mutants at the mating modifier locus, which increase heterotypic fusions but do not lower the homotpyic fusions relative to the resident allele at the object locus, generally replace the resident allele.

We establish the conditions when a modifier allele can invade and when it becomes fixed if sufficiently frequent.

This threshold value is pivotal in determining whether the spread of a modifier allele causes the extinction of Wolbachia and was confirmed by simulation.

We ran two types of simulations: those with populations homogeneous at the modifier loci; and those of modifier allele invasions.

Further investigation of this variant as a low-penetrance modifier allele might be warranted.

It thus acts as a mating modifier whereas the first locus plays the role of the object of selection and mating.

Prior to the appearance of any mating modifier, "simple" overdominance (v11 < v12 > v22) is sufficient for a stable B-polymorphism.

Invasion was successful if the invading modifier allele took over the population significantly more often than expected for a neutral modifier (teh expected invasion success of a neutral allele is its initial frequency, 1% or 5%).
