  2. Seperation of male and the female gamete

  3. Both A and B

  4. Foetus formation

A Correct answer
Explanation

Fertilization in humans is the fusion of female gamete and a male gamete in the ampulla of the oviduct. The result is the production of a zygote or fertilized egg.
Thus, the correct answer is option A.

The life span of an unfertilized egg is

  1. Two days

  2. One hour

  3. One day

  4. One week

C Correct answer
Explanation

Every month, the egg is released from the ovary and moves into the fallopian tube for fertilization and if the egg is not fertilized during that time, it disintegrates. The life span of that unfertilized egg is 24 hours or one day after it has left the ovary. So, the correct answer is option C.

Mature mammalian follicle is known as

  1. Graffian follicle

  2. Ovarian follicle

  3. Corpus luteum

  4. Corpus albicans
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The female mammals are characterized by cyclic changes in reproductive tract and ovaries, regulated by some hormones like FSH and LH. Every month, one ovarian follicle matures, ruptures and releases its ovum into the peritoneal cavity and this ovarian follicle is called as Graffian follicle. Therefore, the term Graffian follicle is used for a mature follicle in the mammalian ovary.

So, the correct answer is option A.

The region of female reproductive tract where fertilization occurs is

  1. Vagina

  2. Uterus

  3. Cervix

  4. Fallopian tube
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The egg released from the mature Graafian follicle enters the fallopian tube through the ostium. The egg waits in the ampulla region of the fallopian tube for the sperm. The process of fertilisation is te fusion of the male and the female gametes which take place in the fallopian tube.

Thus, the correct answer is option D.

Fertilisation means

  1. The shedding of gametes from a reproductive organ

  2. Adhesion of male and female reproduction organs

  3. Fusion of nuclei of male and female gametes

  4. Transfer of male gamete to female gamete

C Correct answer
Explanation

  • Fusion of male and female gamete is a key step in reproduction. This is known as fertilization.
  • Fertilization results in zygote which later develops into embryo.
So, the correct option is 'Fusion of nuclei of male and female gametes'.

Fertilization means

  1. Fusion of male and female nuclei

  2. Fusion of two female nuclei

  3. Interaction of male and female reproductive organs

  4. Fusion of two male nuclei
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Fertilization is the process in which haploid male and haploid female gamete fuse together to form a diploid zygote. This process is also known as syngamy. In this process, the nucleus of the male gamete fuses with the nucleus of the female gamete to promote the fusion of their genetic material. So, the correct option is A.
