2 inbred mice strains A,B express different alleles only at minor histocompatibility complex locus on Y chromosome. Which mice would accept a skin graft from a male (AxB)F1 mouse with strain A father and strain B mom?
1.AxB F1 female (A mom B dad)
2.AxB F1 female (A dad, B mom)
3.AxB F1 male (A mom, B dad)
4.AxB F1 male (A dad, B mom)

I just picked 4 because hes the same as the person giving the skin graft.

  #2

right , thats the reason why I would also pick 4

  #3

I covered your answers and after reading it I said 4 too for the same reason... but don't know if there are any other strange things to consider...

  #4

I got this one wrong .. !!
But now that I see it .. 4. is probably the correct answer and the donor and the reciever would be the same .. !! ANd I guess they were askin that ONLY .. !! shocked
