The octopus just revealed another one of its secrets: what determines its sex. University of Oregon researchers have ...

Discover how researchers identified an octopus' ancient sex chromosomes and why their genetic history is such a mystery.

The research suggest octopus and other cephalopods, like squid and cuttlefish, all rely on the ancient chromosome to ...

The paper B.A. Sandkam et al., “Extreme Y chromosome polymorphism corresponds to five male reproductive morphs of a freshwater fish,” Nat Eco Evol, 5:939–48, 2021. One of the key stages in the ...

Scientists have made an exciting discovery about octopuses: they have one of the oldest known sex chromosomes in the animal ...

Searching the octopus genome had shown no clear sign of a sex chromosome system. Scientists were beginning to wonder if ...

The chromosomes were then arranged into a karyotype ... so it is not possible to define the translocation breakpoints. Nonetheless, FISH is useful because it can reveal small translocations ...

P1 and PAC clones specific for all human subtelomeric chromosome regions 17. We describe here the development of a 12-color FISH assay for telomeric rearrangements (termed M-TEL) using an updated ...

Researchers have identified a sex chromosome in the California two-spot octopus. This chromosome has likely been around for 480 million years, since before octopuses split apart from the nautilus on ...
