Q

How many chromosomes are present in a human gamete?

A

23.

17
Q

Fill in the blank: The process of sperm formation is called __________.

A

spermatogenesis.

18
Q

What is a primary oocyte?

A

An immature female gamete that undergoes meiosis.

19
Q

Multiple Choice: At what stage does a primary oocyte complete meiosis I?

A

C) Just before ovulation

20
Q

What is the role of follicle-stimulating hormone (FSH) in females?

A

To stimulate the growth of ovarian follicles.

21
Q

True or False: Both spermatogenesis and oogenesis occur continuously throughout an individual’s life.

A

False

22
Q

What is the significance of polar bodies in oogenesis?

A

They are byproducts that allow the ovum to retain most of the cytoplasm.

23
Q

Fill in the blank: The stage of sperm development where the tail forms is called __________.

A

spermiogenesis.

24
Q

What is the main difference between spermatogenesis and oogenesis?

A

Spermatogenesis produces four functional sperm, while oogenesis produces one functional ovum.

25
Q

Multiple Choice: Which hormone is primarily responsible for the development of male secondary sexual characteristics?

A

A) Testosterone

26
Q

What is the duration of the entire spermatogenesis process?

A

Approximately 64 to 74 days.
