Sample questions

1. The fusion of male and female gametes is known as:

   1. Ovulation
   2. Gestation
   3. Fertilization
   4. Menstruation
   Show answer

   Answer: C. Fertilization

   Fertilization is the process where a male gamete (sperm) fuses with a female gamete (ovum) to form a zygote.

2. Oviparous animals are those that:

   1. Give birth to live young
   2. Lay eggs
   3. Reproduce asexually
   4. Undergo external fertilization
   Show answer

   Answer: B. Lay eggs

   Oviparous animals are animals that reproduce by laying eggs, from which offspring develop.

3. What structure is formed when a sperm fuses with an ovum?

   1. Embryo
   2. Zygote
   3. Gamete
   4. Fetus
   Show answer

   Answer: B. Zygote

   The zygote is the initial cell formed when two gametes (sperm and egg) fuse during sexual reproduction.

4. Which of the following is a characteristic of sexual reproduction?

   1. Only one parent is involved
   2. Offspring are genetically identical to the parent
   3. Requires fusion of gametes
   4. Faster than asexual reproduction
   Show answer

   Answer: C. Requires fusion of gametes

   Sexual reproduction always involves the fusion of male and female gametes, leading to genetic diversity.

5. Which of the following organs is primarily responsible for producing female gametes (ova) and female sex hormones?

   1. Uterus
   2. Fallopian tubes
   3. Ovaries
   4. Vagina
