Question

The process of production of gametes is called ________​

Answer 1

Answer:

$}{gametes} is right answer$

Explanation:

Gametes are formed through meiosis (reduction division), in which a germ cell undergoes two fissions, resulting in the production of four gametes. During fertilization, male and female gametes fuse, producing a diploid (i.e., containing paired chromosomes) zygote.

Answer 2

Answer:

• The process of production of male gametes or sperm is called spermatogenesis.
• The process of production of female gametes or egg is called oogenesis.

Explanation:

Spermatogenesis

• The production of sperm from immature germ cells is called spermatogenesis.
• During this process, a diploid spermatogonium (male germ cell) becomes a diploid primary spermatocyte by increasing its size.
• This primary spermatocyte undergoes the first meiotic division to form two equal haploid secondary spermatocytes.
• Each secondary spermatocyte undergoes a second meiotic division to form two equal haploid spermatids.
• These spermatids change into spermatozoa (sperm) by the process of spermiogenesis.

Oogenesis

• The process of oogenesis takes place through three steps.

• Step 1 – Pre-natal stage
• During this stage, the primary oocyte grows and stops in meiosis.
• The follicular cells proliferate and form granulosa cells.
• These secrete glycoproteins around the primary oocyte.

• Step 2 – Antral stage

• In between the granulosa cells, there is a fluid-filled area which combines to form an antrum.
• They are called secondary follicles.
• Every month, these secondary follicles develop due to follicle stimulating hormone and luteinizing hormone.

• Stage 3-Pre-ovulatory stage

• Two haploid cells of unequal sizes are formed.
• These two cells undergo meiosis-II.
• The polar body duplicates to form two polar bodies, while the secondary oocyte stops in the metaphase stage of meiosis-II.
