Brown eyes are dominant over blue eyes. if a woman with a dominant brown eyes ,(homozygous) reproduces with a man with recessive blue eyes , what is the chance they will have a child with brown eyes?

The chances are 100%

Explanation:

A dominant allele is the allele that expresses itself in the offspring even if it is present in heterozygous condition(Bb). So when a woman with homozygous dominant(BB) condition of brown eyes reproduces with a man having recessive blue eyes(bb) then all the offsprings with heterozygous dominant condition for brown eyes will be produced.

                               B      B

                           b  Bb   Bb

                           b  Bb    Bb

All the offsprings will have one dominant allele which is enough to produce brown eyes therefore all the offsprings will have brown eyes. So the chances are 100%.

i think that d. wind is the answer.   i missed the question when i answered a. currents.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
