genes in aplysia slugs

Post by coco » Sun Jun 25, 2006 5:43 pm

the discovery of a gene in aplysia slugs that results in protein products including egg-laying hormone is evidence that:

1 the egg-laying behaviour is innate or hardwired into the slugs brain
2 the egg-laying behaviour has absolutely no nervous system involvement
3 genes can control endocrine gland secretions that can control behaviour
4 this slug could avoid being eaten by garter snakes
5 genes only influence physiology and structure but not behaviour

i think the correct answer is 3, but im not 100% sure, i need some opinions
thank you,

I agree. I think 3 is the most likely.

2, 4 and 5 are almost certainly wrong and I think 3 is more likely than 1.
