Today's Google Doodle: Who was Nettie Stevens?

[femmocrat]

Happy 155th Birthday, Nettie!



Nettie Stevens — who’s honored in today’s Google Doodle — lived at the end of the 1800s, at a time when women mostly married and stayed home, or were teachers or nurses if they wanted to work. Instead, Stevens became a research scientist and her discoveries changed genetics forever.

Stevens was interested in understanding how a person, or animal, is born male or female. She began studying chromosomes — thread-like structures that keep DNA molecules inside the nucleus of cells. And she became one of the first scientists to find that sex is determined by a particular combination of the sex chromosomes X and Y.

1. Thanks for this informative post, my dear femmocrat!

She was something else, wasn't she?

I was aware of the science, but not of the scientist...

5. Birds do it differently.

In birds the males have the homomorphic chromosomes, equivalent to XX in humans, and the females are XY.

So they changed the letters.

Male birds have ZZ chromosomes, female birds have ZW chromosomes.

6. there was never anything wrong with being "teachers or nurses"

what was wrong was that women were LIMITED to these professions
