Question

Which of the following is most SIMILAR between oogenesis and spermiogenesis?

Group of answer choices

The number of viable gametes produced

The age at which a person starts producing gametes

The timing of meiotic divisions

The size of the viable gametes produced

The hormone system that drives the production of gametes

Answer 1

ANSWER

3.The timing of meotic division

Both process shows meiosis in maturation phase and produce haploid gametes.

Explanation.

Spermatogenesis is the process in which spermatozoa produced from spermatogonial stem cells by way of mitosis and meiosis.

Oogenesis is the process through which (ova) female gametes are formed and this female gamete is known as an ovum.

During Meosis I, both primary spermatocyte and oocyte undergo division.  

• Primary spermatocyte - 2 secondary spermatocyte
• Primary oocyte - 1 secondary oocyte and 1 polar body.

Explanation for wrong answers:

1.Spermatogenesis produces four haploid sperm cells, while oogenesis produces one mature ovum.

2.Age at which person produce gamates differ in males and females. Females will attain puberty before males of same age.

4.The egg is among the largest cells in an organism, while the sperm ( spermatozoa) is often the smallest.

5. Hormones driving in gamate production varies

Males - Testosterone.

Females - Estrogen and Progesterone.
