Partial amniote sex chromosomal linkage homologies shared on snake W sex chromosomes support the ancestral super-sex chromosome evolution in amniotes
W Singchat, SF Ahmad, S Sillapaprayoon… - Frontiers in …, 2020 - frontiersin.org
Squamate reptile chromosome 2 (SR2) is thought to be an important remnant of an ancestral
amniote super-sex chromosome, but a recent study showed that the Siamese cobra W sex
chromosome is also a part of this larger ancestral chromosome. To confirm the existence of
an ancestral amniote super-sex chromosome and understand the mechanisms of amniote
sex chromosome evolution, chromosome maps of two snake species [Russell's viper:
Daboia russelii (DRU) and the common tiger snake: Notechis scutatus (NSC)] were …
