Answer:
11. bb
12. BB
13. XᵇXᵇ
14. XᴮY
15. Bb
Step-by-step explanation:
b is recessive, someone needs 2 of them to express the trait
B is dominant, someone needs 1-2 of them to express the trait
XX is female, b needs to be on both of the X for the female to express the trait
XY is male, traits are always on the X chromosome, so males need a dominant trait to be on the X for the trait to be expressed
A carrier is someone that has the trait, but doesn't express the trait physically
