BIO HELP 10 POINTS (if you're right then you get brainliest)
The role of the mRNA molecule is to

create an additional copy of the genetic code to be used in case of DNA degradation.
carry the genetic code out of the nucleus to the ribosome for translation to occur.
read the strand of amino acids to determine where the protein should start and stop.
bring the correct amino acids to the codons on the DNA strand.

The answer would be c, white eyes are homozygous recessive. in the early 1900s, morgan conducted several experiments with vinegar  flies (drosophila). one  sample revealed an anomaly: a  white-eyed, single male fly. he attempted to breed this fly with the typical red-eyed females. the offspring were all red-eyed. using flies from this new generation (brother-sister pairs)  produced some red-eyed and a few white-eyed flies. the white-eyed were all male. in later experiments, he was able to produce white-eyed females. this proved that white eyes are not lethal to either sex (ruling out a and b). since the percentage of white eyes to red eyes is so low, white eyes are not a dominant trait. it would be a recessive trait.
