Was the Neanderthal Y chromosome toxic in hybrid boys?
Another chance is that the Neanderthal Y chromosome won’t work with qualities on different chromosomes from present-day people. The missing Neanderthal Y may then be made sense of by “Haldane’s Rule”. During the 1920s, English scientist J.B.S. That’s what Haldane noticed, in half and halves between species, assuming one sex is fruitless, uncommon or undesirable, it is consistently the sex with not at all like sex chromosomes.
In well evolved creatures and different creatures where females have XX chromosomes and guys have XY, excessively male mixtures are ill suited or fruitless. In birds, butterflies and different creatures where guys have ZZ chromosomes and females have ZW, it is the females.
Many crosses between various types of mice show this example, as do cat crosses. For instance, in lion-tiger crosses (ligers and tigons), females are prolific however guys are sterile. We actually miss the mark on the great clarification of Haldane’s standard. It is one of the getting through secrets of exemplary hereditary qualities.
In any case, it appears to be sensible that the Y chromosome from one animal category has developed to work with qualities from different chromosomes of its species, and probably won’t work with qualities from connected animal types that contain even little changes.
We realize that qualities on the Y develop a lot quicker than qualities on different chromosomes, and a few have capabilities in making sperm, which might make sense for the fruitlessness of male half-breeds. So this could make sense of why the Neanderthal Y got lost. It likewise raises the likelihood that it was the shortcoming of the Y chromosome, in monumental a regenerative hindrance, that Neanderthals and people became isolated species in any case.
