AbstractApes possess two sex chromosomes—the male-specific Y and the X shared by males and females. The Y chromosome is crucial for male reproduction, with deletions linked to infertility1. The X chromosome carries genes vital for reproduction and cognition2. Variation in mating patterns and brain function among great apes suggests corresponding differences in their sex chromosomes.

IntroductionTherian X and Y chromosomes are thought to have originated from a pair of autosomes approximately 170 million years ago (MYA)1. The X chromosome, typically present in two copies in females and one copy in males, has mostly retained the gene content and order from the original autosomal pair2.

AbstractThe eastern quoll (Dasyurus viverrinus) is an endangered marsupial mesopredator native to Australia. Since the extirpation of the last mainland Australian populations in the late 20th century, wild populations of this species have been restricted to two islands at the far southern end of its historical range. Eastern quolls are the subject of captive breeding programs and attempts have recently been made to re-establish a population in mainland Australia through translocations.
