Question

In female Drosophila, the linked gene exhibit recombination during meiosis of gamete formation, but such a recombination does not occur during the formation of sperm in male Drosophila because

• A. Male Drosophila is sterile
• B. Male Drosophila is parthenogenetic male
• C. No crossing over occur in male Drosophila
• D. Male Drosophila is haploid

Answer 1

The correct option is C No crossing over occur in male Drosophila

Recombination is the phenomena of formation of traits by the combination of parental traits. It takes place during meiosis by chiasmata which are absent during the formation of sperm in male Drosophila as it shows complete linkage and hence does not show cross over.

So, the correct answer is option C.
