What is the number of chromosomes (n) present in the gametes?

Gametes are haploids, therefore contain exactly half the number of chromosomes as a normal cell.For humans a normal cell contains 23 pairs (46) chromosomes, therefore a human gamete (egg or sperm) contains 23 chromosomes. In terms of  n, a normal cell has 2n, therefore a gamete has just n

Um can u take a picture of the work

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.
