Sentence examples for poor mate from inspiring English sources
Fitter ciliates compensate for their poor mate selection via cytoplasmic exchanges that reinstate the wildtype phenotype to conjugated mutants incapable of performing programmed movements.
Third, conditions causing diminishing male returns are low density and mobility or poor mate searching (Tomlinson 1966; Ghiselin 1969), which reduce sperm competition and thus favour low male investment (Fischer 1984; Raimondi & Martin 1991; Schärer & Ladurner 2003).
Given the highly female-biased sex ratio, generally poor mating-ability of C. elegans males, and frequent monitoring, we assume that a mated female was inseminated only once.
Because aberrant regulation of these genes makes these two mouse species such poor mates, zoologist Wallace Dawson of the University of South Carolina, Columbia, thinks of Peg3 and Plp as "speciation genes".
As an example of poor mating performance, males of strain RS5212 produced cross progeny with only 30% of the mated hermaphrodites.
Poor mating or low ascospore count can sometimes result from random technical problems, such as a low medium level in (or poor conidial transfer to) a given well.
We find that, similarly to C. elegans, P. pacificus males are generated at low frequencies from self-fertilizing hermaphrodites and are relatively poor mating partners.
Furthermore, C. elegans isolates derived recently from the wild seem to counterselect males due to outbreeding depression [ 33], low non-disjunction rates and relatively poor mating ability [ 32].
A minimum of ten wild-type males on one plate was considered sufficient to conclude that the absence of Dpy Unc animals was not due to poor mating.
Alternatively, poor mating success between lineages could also play a role, either due to divergent reproductive ecology, or to some level of genetic incompatibility.
