Question

Meiosis during sperm formation of Ascaris, was first observed by

• A. Fleming
• B. Boveri
• C. Brauer
• D. De Vries
• E. Abbe

Answer 1

The correct option is C Brauer

The formation of sperm from stem cells of testes is known as spermatogenesis. One sperm mother cell first undergoes mitosis and forms primary spermatocyte.

The primary spermatocytes then undergo meiosis 1 and form two secondary spermatocyte. The spermatid then undergoes meiosis II and thus form 2 spermatids each. This was first observed by Brauer in sperm formation of Ascaris.

So, the correct option is 'Brauer'
