When thomas hunt morgan crossed his red-eyed f₁ generation flies to each other, the f₂ generation included both red- and white-eyed flies. remarkably, all the white-eyed flies were male. what was the explanation for this result?
a) the involved gene was on the x chromosome
b) the involved gene was on the y chromosome.
c) the involved gene was on an autosome.
d) other in. ilc-spccific factors influence eye color in flies
e) other fc. nalc-sjxcific factors influence eye color in flics.

The correct answer will be option-A

Explanation:

Thomas Hunt Morgan performed the experiment in 1910 on the Drosophila which explained the role played by the chromosomes in heredity. When Morgan crossed red-eyed flies he observed that F₂ flies included both red ad white-eyed flies in which the males are white-eyed only.

Morgan concluded that the genetic factor which controlled the eye color was present on the same chromosome which determined the sex of the flies. This indicated that the gene in involved on the X chromosome and the male is hemizygous for the trait.

Thus, option-A is the correct answer.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
