haploid stages. This hypothesis would infer a strong selective advantage for a regular return to the haploid stage. In fact, selection on haploid gametes is always quite strong as few gametes, and only the fittest ones, reach syngamy and karyogamy; most of them are lost. In anisogamous ...
However, when a donation of gametes is made, it is with the donor’s consent that no pregnancy will occur with the embryos that are produced. In July of 1997, the Ethics Committee of the Jones Institute met to discuss research on human embryos where transfer back to the uterus was not ...
Previous study demonstrated that the nuclear chromatin of sperm cells contains high quantity of thiol-enriched protamines, and flagella of sperms is enriched with thiols; therefore, the male gametes are vulnerable to arsenic-induced damage60. The capacity of arsenic to attach with the thiol ...
The very recent identification of both nucleophosmin and triose-phosphate isomerase in human serum from normal individuals supports this suggestion (58). It is only possible to speculate why gametes might regulate the secretions of proteins usually involved in intracellular metabolism. The presence of ...
female- being the sex (of plant or animal) that produces fertilizable gametes (ova) from which offspring develop; "a female heir"; "female holly trees bear the berries" male- being the sex (of plant or animal) that produces gametes (spermatozoa) that perform the fertilizing function in gen...
There are two common suppositions which – at least on this basic biological level – are clearly false. The first – that of the passivity of the female – is disproved by the fact that new life springs from the union of the two gametes; the living spark is not the exclusive property ...
Now is the time for these discussions. Human artificial gametes are set to become a scientific reality in the coming years. Just how soon depends on who you ask. “To be very honest, I don’t like to guess,” says Saitou. “With some unexpected roadblocks, suddenly the progress stops, ...
