Nearly every cell in our body contains pairs of each of our chromosomes, and these pairs are identical in all but one case: that of our sex chromosomes. Males typically have one X and one Y sex chromosome, while females typically ...

The sex of human and other mammal babies is decided by a male-determining gene on the Y chromosome. But the human Y chromosome is degenerating and may disappear in a few million years, leading to our extinction unless we ...

Even worms have a ticking fertility clock. Older worms are less efficient at repairing broken DNA strands while making egg cells—part of a process that's essential for fertility. A new study from University of Oregon (UO) ...

In mammals, the distinction between male and female at the chromosomal level is due to the X and Y chromosomes. Typically, females have two X chromosomes (XX) while males have an X and a Y chromosome (XY). The Sry gene on ...

Unlike humans, turtles, lizards and other reptiles—such as crocodiles—do not have sex chromosomes. Their sex is determined based on the environment, which makes them especially vulnerable to climate change. An increase ...

In most higher organisms, including humans, every cell carries two versions of each gene, which are referred to as alleles. Each parent passes on one allele to each offspring. As they are linked together on chromosomes, adjacent ...

The evolution of a new species by hybridization from two already described species without a change in chromosome number is very rare in the animal kingdom. So far, only a few accepted empirical examples exist for this spontaneous ...
