Hey! I have a few questions:
In questions where we are asked to identify the structures of the eye in two animals, for example, would humans be an okay option?
And is there ACTUALLY a difference between independent assortment and random segregation?

THAT WAS AWESOME, Naomi!
Omgosh...I laughed SO MUCH when you told us that we stink. ROFL
Good luck to everyone tomorrow!!! :D

I think the key here is to put them in order of time - when they discovered what they did - and to try to link their discoveries together.

Yo but how are these scientists (apart from Sutton) related to inheritance?

Mendel is the father of genetics, He noticed similar traits between successive generations. The height, colour, pod colour, wrinkly-ness etc. These are all traits and his experiments are all about inheritance.
Beadle and tatum- their experiment was about how a gene controls a polypeptide, experimentally linking how genetics and phenotypes work, therefore it shows how actual physical traits are inherited from the genes given to them from generations above.

Could someone please explain why there are two independent variables in this experiment (it was a 2015 multiple choice question):
Investigate the optimum pH of four different enzymes.
Thanks :)
