A team of researchers have generated the first complete chromosome sequences from non-human primates. Published in Nature, these sequences uncover remarkable variation between the Y chromosomes of ...

A genomic study of human and selected nonhuman primate centromeres has revealed their unimaginable diversity and speed of evolutionary change. In cell genetics, a centromere is the spot where two ...

Birds have a dazzling display of patterns, from muted colors to vivid and striking hues. For a long time, scientists believed that the evolution of these traits was a slow process that took place when ...

The 23rd chromosome base pair contains what are known as our sex chromosomes. For most females, this pair contains two X chromosomes, while for most males, it contains one X chromosome and one Y ...

Johns Hopkins Medicine researchers say they have found that specific variations in three genes related to maintaining the length of telomeres—the protective DNA endcaps on chromosomes—may explain up ...

Human sex chromosomes originated from a pair of autosomes, the ordinary or non-sex chromosomes that contain the majority of our genome and come in identical pairs. That ancestral pair of autosomes ...

Madagascar began rebuilding a giant tortoise population in 2018 with only 12 founder animals at the Anjajavy Reserve in the ...
