What is a key difference between spermatogenesis and oogenesis?

Correct answer: D. Spermatogenesis results in 4 sperm; oogenesis results in only 1 functional egg

  • A. Spermatogenesis results in only 1 sperm; oogenesis results in 4 eggs
  • B. Spermatogenesis results in 2 sperm; oogenesis results in only 1 egg
  • C. Spermatogenesis results in 8 sperm; oogenesis results in only 4 eggs
  • D. Spermatogenesis results in 4 sperm; oogenesis results in only 1 functional egg

Explanation

Spermatogenesis is the process of producing sperm cells, which results in the formation of four functional sperm cells from one primary spermatocyte. On the other hand, oogenesis is the process of producing egg cells, which results in the formation of one functional egg cell from one primary oocyte. Therefore, spermatogenesis results in four sperm cells, not eight, while oogenesis results in one egg cell, not four.Spermatogenesis is the process of producing sperm cells, which results in the formation of four functional sperm cells from one primary spermatocyte.
