Sock/shoe, sock/shoe usually. I never wear socks unless I am putting on shoes to leave the house, so i collect the socks and shoes I'm wearing and put them on all at once right before I leave. Sock/shoe, sock/shoe minimizes the possibility of my socks picking up stray hair/lint/etc and shoving it into my shoes.

The X-inactivation originally happens in individual cells, but it happens during embryonic development and is maintained through cell division. The cells divide many, many times after that point, leading to the regions of shared inactivation you see in the black/orange patterning of tortoiseshell cats. There’s another gene (not X-linked) that can add white spotting to the mix, combined they make calico cats.

Sex-linked traits were first described by TH Morgan in fruit fly eyes 40-50 years after Mendel published his pea experiments. It was the first published finding that specifically linked a gene to a chromosome, providing considerable evidence for the chromosome theory of inheritance which was still hotly debated at the time.
