Answer:

A homozygous brown mussel crosses with a blue mussel. The percentage of offspring are expected to be blue 0%

Explanation:

homozygous brown means BB= which is dominant

while the blue mussel too is bb= homozygous blue recessive  

After crossing, it would result into having Bb, Bb, Bb, Bb which are all heterozygous dominant brown which is 100% brown because the colour brown is dominant over the blue colour.

0%
All of them will have a genotype of Bb, so none of them will be expected to be blue
