Question

Write the correct genotype. Use B or b for alleles

Answer 1

Answer:

11. bb

12. BB

13. XᵇXᵇ

14. XᴮY

15. Bb

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
