Question

An organism with the genotype TtSs can normally make all of the following gamete combinations except: A:TS B:TT C:Ts D:tS

Answer 1

it is B:TT

Step-by-step explanation:

I took the test and got it correct and also the other guy that answer also said it was TT

Answer 2

When you are considering a genotype two dominant and recessive genes, they can only make the combinations between the two and cannot between each other. For example, the possible combinations that can be made with the genotype you asked is as followed: TS, Ts, tS, ts.

Meaning that TT cannot be one of the combinations, as it needs to include the second trait. Which would be B.
