The alleles for brown eyes (b) are dominant, while those for blue eyes (b) are recessive. if lesley’s mother has the genotype bb and her father has the genotype bb, what is lesley’s genotype? what is her phenotype?

Her genotype is Bb and her phenotype is brown eyes.

This is because, if you create a punnet square, every square should be filled with the gentoype of Bb which results in the phenotype of brown eyes.

Hope this helps!

the father in the first generation probably had the recessive colorblind trait in his x chromosome. if he and his wife both had the colorblind trait, even if she had 1 recessive and 1 dominant, then that trait would be passed on to their kids.

(since you didn't attach the family tree this is just an assumption)

the answer for this question would be d. glaciers
