Question

A brown-eyed man (whose mother has blue eyes) marries a brown-eyed woman (whose father had blue eyes).

Is it possible for them to have a blue-eyed child? Why or why not? Explain your thinking.
Bonus: What alleles might be present in their child? Use capital and/or lowercase letters to write the alleles. For example BB, Bb, or bb.

Answer 1

Step-by-step explanation:

BB- Brown

bb- blue

Bb- Brown (heterogeneous)

Bb × Bb

B b B b

BB Bb Bb bb

25% BB

50% Bb

25% bb

so there's 25% possibility to have a blue eyed child

and 25% chance to have a homogenous (BB) Brown eyed child. so the future does not have any blue coloured eye

and 50% chance to get heterogeneous (Bb) Brown coloured eye child.

Answer 2

yes

Step-by-step explanation:

yes because in this specific scenario the gene could have skipped the two brown eyed people and may be passed on to their child. (this happened with my cousin and i did this exact question so i was able to help)
