@myschool the answer is supposed to be D because;
X*X and X*Y would produce ;
X*X* X*Y X*X XY
Hence the ratio of carriers to sicklers is 1:2💯✔️ please take note
The parents are carriers AS
The cross btw the parents will produce AA AS AS SS
The ratio of the carriers to stickler in the offsprings is 2:1
The question itself is not specific, because it did not specify that whether it is a phenotypic or genotypic ratio
chai. tricky
TT* TT*
TT. TT* TT* T*T*
The carrier are
TT* TT* T*T*
WHICH IS 2:1.
WOW!
U guys are the limit.u asked the ratio of ss to carriers and u r answering the ratio of carriers to ss.when u cross two sickle cell carriers u get one AA,two AS,and one SS.
I can't tell whether u guys are doing this purposely but u r leading people astray.I wish u guys could be disciplined for this.
