Answer:
True
Explanation:
The Drosophila like the mammals possess X and Y chromosomes but as in males in which the XX is female and XY is male, the sex In Drosophila is not determined by the presence of Y chromosomes as a male determining factor are present on the autosomes.
However, the Y chromosome is important for males as they are involved in the formation of the sperms therefore the presence of Y is important. In the given question if the allele is present ion the Y chromosome which can reduce the size therefore the allele is passed on to the males only ans no females.
Thus, true is the correct answer.
the fly is female (Bridges 1921, 1925). Thus, XO Drosophila are sterile males. In flies, the Y chromosome is not involved in determining sex. Rather, it contains genes active in forming sperm in adults.
<span>Open-mindedness does interfere with scientific progress as it can lead to acceptance of untested ideas. Open-mindedness can lead to actually accepting results that are not true. This is not a great angle for people involved with scientific experiments. Open-mindedness should be limited to the fact that the results can lead to negative answers. People that can accept this theory will ultimately succeed in their strive for creating something new. There is nothing wrong in discarding the results that does not seem to fit the bill.
