I need answers pls, help me brainliest ko po maka ans ng tama, report nonsense thanks.

The offspring are all black eye colored.

Explanation:

Since we have genes BB for black eye color and genes bb for brown eye color, crossing the genes, the resulting genotypes in the offspring is Bb, Bb, Bb and Bb. We note that all the genes have the dominant B gene. Since the black eye color dominant gene is present in all the offspring, the offspring are thus all black-eye colored.

So, If you will cross a parent with black eye color (BB) and the other is

brown eye (bb), the offspring are all black eye colored.
