Sentence examples for sperm model from inspiring English sources

To this end, we set up a plasma membrane-permeabilized mouse sperm model similar to the one we routinely use for human sperm [16], [17].

Cryptic female choice on sperm length is supported by a genetic correlation between spermathecal size and sperm length congruent with the sexy sperm model, and by an interaction between these two traits in determining paternity success [14], [16].

The genetic relationship between sperm length and male condition suggests that the good sperm model, which requires genetic integration between competitive fertilization success in males and offspring viability [32] is also plausible.

We have taken advantage of the versatility of the sperm model to investigate how cAMP, calcium, and the proteinaceous fusion machinery coordinate to accomplish secretion.

Luckily, we were able to exploit a remarkable feature of our permeabilized sperm model that confers the ability of reversibly halting calcium-triggered exocytosis at specific stages (with reagents that we will refer to as "inhibitor 1").

Importantly, both the sexy-sperm and the good-sperm model are based on additive (intrinsic) effects of genes influencing a male's sperm competitiveness [ 10, 11].

For instance, testing the good-sperm model in phenotypic studies relies on the correlation between a male's sperm competitive ability and his offspring viability [ 9, 44].

We conducted two separate experiments to test Parker's [4] sperm competition model.

If males possess similar kin discriminative abilities, they do not appear to respond to this information, at least in the context of Parker's [4] sperm competition model.

Since the development of Parker's [4] sperm competition model, it has become apparent that strong competition between relatives can act as an opposing force to kin selection [10], [11].

Parker's [4] sperm competition model examines the effects of relatedness between competing males on sperm allocation at any particular mating, and predicts that males should exhibit a conditional shift in behavior, transferring less sperm if his male rival is a full sibling.
