Sentence examples for decrease outcrossing rates from inspiring English sources
Both processes can decrease outcrossing rates and genetic variation in remnant stands.
The outcome of these interactions is that a single clone may eventually competitively exclude other clones, potentially decreasing future sexual reproduction by decreasing outcrossing potential.
However, we expect that in cases where Brassica hybrid fecundity is restored in backcross generations (see, for example, Jørgensen et al., 2009; Snow et al., 2010) the dependence on the parental species would decrease, whereas higher outcrossing rates would further increase dependence on the parental seed bank dynamics.
The fragmentation of plant populations may decrease seed production and outcrossing rates due to limitations of mates and pollinators in the remaining, fragmented populations, potentially reducing reproductive success [ 1, 2].
Consequently, if repeated mating of hermaphrodites did occur in the experimental populations, then the higher costs (i.e. offspring loss) of copulations with multiple males for N2 should decrease male frequencies and thus outcrossing rates to a larger extent in N2 than CB4856.
The observed heterozygosity was significantly correlated with outcrossing rates among populations (r2 = 0.783; P<0.001) although no obvious correlation between outcrossing rates and genetic diversity parameters was observed.
Pollen movement was also evaluated by the analysis of outcrossing rates using seven nuclear microsatellites.
The outcrossing rates thus estimated are found to agree well with those directly extracted from Monte Carlo simulation.
We halved worms before in vitro breeding and evaluated whether this affected outcrossing rates and reproductive output.
Yeasts can replicate by sexual and asexual reproduction but have relatively low outcrossing rates (Tsai et al. 2008).
We find that current prescriptions for field trials are likely to lead to escape of transgenes into wild populations when outcrossing rates are moderate and hybrids are fertile.
