Sentence examples for mating frequency of from inspiring English sources

This remating interval was chosen to conform to the natural lifetime mating frequency of field-collected females [ 49].

The lifetime mating frequency of males is usually > 10 times higher than that of females (Schulten, 1985).

To examine the hypothesis that N2 hermaphrodites actively resist mating with males, we quantified hermaphrodite mating frequency of N2-derived mutants defective in neural function.

Relative mating frequency of non-target pairs remained more or less constant among treatments (mean: 0.28 ± 0.02) and was not significantly affected by density or species.

To estimate the maximum and mean mating frequency of males, we placed 1 day old ergatoid (n = 6) and winged males (n = 5) individually in nest chambers with ten to 20 female sexuals, approximately 15 workers, and some brood each.

Early work on Drosophila spp. revealed that flies heterozygous for certain inversions showed superior fitness and developmental homoeostasis compared with their homozygote counterparts (Dobzhansky and Wallace 1953; Spiess and Langer 1966), which was correlated to increased courting and mating frequency of heterozygote males (Brncic and Koref-Santibanez 1964).

Removing unmated control males from the analysis revealed a positive effect of mating frequency on accessory gland length (b ± s.e. = 0.0228 ± 0.0086, t149 = 2.67, p = 0.0085) after controlling for the significant effect of recovery time (F4,149 = 3.38, p = 0.0111).

Intriguingly, we found opposite effects on mating frequency for two sets of sensory neurons expressing TAX channels.

To find out what genetic differences underlie natural variation in hermaphrodite mating frequency, we generated a panel of RILs by interbreeding the N2 and HW wild-type isolates and mapped mating frequency to SNP markers spread across the C. elegans genome (see File S2).

Female fitness is thus a direct function of mating frequency irrespective of male quality.

Below the diagonal are values for the IPSI of Rolán-Alvarez and Caballero [ 78] testing for sexual isolation in 2 × 2 tables of mating frequency among all pairs of five Physa populations, and above the diagonal are the grand totals of the copulations upon which the statistic is based, of 60 maximum.
