Which of the following sets of features is common to BOTH spermatogenesis and oogenesis in humans?
Options
- AInitiation at puberty and regulation by anterior pituitary gonadotropins.
- BFormation of haploid gametes through equal meiotic divisions.
- CContinuous meiotic divisions and differentiation of the gamete after the completion of meiosis.
- DProgression through multiplication, growth, and maturation phases, and regulation by luteinising hormone (LH)
Correct answer
D. Progression through multiplication, growth, and maturation phases, and regulation by luteinising hormone (LH)
Step-by-step solution
Spermatogenesis and oogenesis both consist of three distinct phases: multiplication, growth, and maturation. Both processes are regulated by the gonadotropins, LH and FSH, secreted by the anterior pituitary. The other options are incorrect because: 1. Oogenesis is initiated during embryonic development, whereas spermatogenesis begins at puberty. 2. Oogenesis involves unequal meiotic divisions, resulting in the formation of a large oocyte and small polar bodies, unlike the equal divisions in spermatogenesis. 3. Ooge
