SO CONFUSING

[rachid.kam]

my sac question today gave me such a hard time. it said "drosiphila flies are used in genetic studies because of a simple genome. why can they be used and why can humans not be used? Also, another gave me alleles TTBBxTTBB and i had to state no of gametes and number of f2 phenotypes.

Isnt the answer to the first one simply because the human genome is MUCH more complex than a drosiphila fly? Hence they have spent years mapping out the human genome, known as the human genome project

Can answer the 2nd one as well just not sure how to on a forum as it requires a punnett square

Just to add to the first one.

There are heaps of reasons that we use Drosophila, but the one that stands out for me is that they're a lot more practical to use than humans. When was the last time you rounded up 1000 humans, forced them to breed, then forced them to inbreed with their parents?

The correct answer is never.
