Male deer have large antlers that are used to challenge each other in fights for territory and females. The females of this group actively choose the strongest males. Which type of sexual selection is occurring with the deer population?

Both inter and intra sexual selection is taking place in the given case.

Explanation:

Intersexual and intrasexual selection are the two fundamental kinds of sexual selection. Intersexual selection takes place due to the association between the males and females of a similar species. In this form of selection, males develop certain traits to fascinate the opposite sex.  

On the other hand, intrasexual selection takes place between same-sex individuals. In this form of selection, competition takes place between the males, like deer with large antlers fight for supremacy and to mate with the females. Both these forms of selection help in the origination of sexually selected features in various species. Hence, in the mentioned deer population, both intersexual and intrasexual selection is taking place.  

from the original order (top to bottom) the new order will go

3 (next generation)

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
