Where we are in the T2T Genomes Era, Pt 2. T2T Sex Chromosomes
Scott Edmunds - May 7, 2025
Following our previous DNA Day 2025 post covering where we are in the T2T (telomere-to-telomer) genomes era, we have a second expert Q&A covering the topic, this time from Kateryna Makova on the challenges (and opportunities) of assembly of T2T sex chromosomes. Lets Talk about Sex Chromosomes Kateryna Makova is the Verne M. Willaman Chair […]
Sex chromosome madness in the iconic echidna
Hans Zauner - January 10, 2025
This week we published a new, high-quality genome sequence of one of Australia’s most iconic animals, the short beaked echidna. The almost gapless genome sequence of this egg-laying mammal helps researchers to track genomic reshuffling events that gave rise to a perplexing sex determination system. At first glance they may be mistaken for a weird-looking […]
Cracking sex chromosome evolution via egg-laying birds and mammals
Scott Edmunds - January 7, 2021
Ducks, Emu’s, Platypus and Echidna’s, oh my! New work on the duck and other egg-laying animal genomes helps crack sex chromosomes evolution and diversity in a number of bird and monotreme species.
Sequencing The Eastern Yellow Robin: Sex chromosomes with a twist
Hans Zauner - September 4, 2019
An Australian team at Monash University discovered unusual, so-called neo-sex chromosomes in the genome of the Eastern Yellow Robin.
