Drosophila Melanogaster... Help Me Out

Post by JYK830 » Fri Nov 10, 2006 3:50 am

I have Vestigial, Wild, and Baride.

P1 Generation Crosses

VM x WF
VM x BF
WM x BF
WM x VF
BM x WF
BM x VF

I have six crosses. M indicates male and F indicates female.

I have no idea what I'm getting for F1.

Please help me out...

Is it depends upon sex linked inheritance?

Which is dominant in Baried and vestigial?

Is baried due to hybrid?

I'm sorry about the late update.

All flies start out as purebred.

I've got a problem with BM x WF.

Outcomes for F1 should be BM, BF, WM, and WF.

However, I only got BM and BF.

I thought baride wasn't dominant? It's supposed to be sex-linked.

Help!!!

By the way, the purpose of my lab is to figure out traits for baride, wild, and vestigial.

if, from a cross between BM and WF you obtained only BM and BF in F1, and you know that the traits are sex-linked, then the normal conclusion is that baride is dominant over the wild type(which is a strange, but not impossible case).
