Question

What is a primary difference between sperm and egg production?

• A. Oogenesis results in four viable ova which are larger than sperm.
• B. Spermatogenesis results in four, equal-sized, viable spermatids.
• C. Production of oocytes starts at puberty but spermatid production begins at birth.
• D. The chromosome number of sperm cells is haploid while the egg cell is diploid.

Answer 1

The correct option is B Spermatogenesis results in four, equal-sized, viable spermatids.

• Oogenesis results in only one viable ovum which are larger than sperm.
• Production of oocytes starts in embryonic life while sperm production starts at puberty.
• Both sperm cells and egg cells are haploid.
• Hence, options A, C and D are incorrect.
• So, the correct option is 'Spermatogenesis results in four, equal-sized, viable spermatids.'.
