  • Question 1
    1 / -0.25

    The population of vagina with semen during coitus is called as _______

    Solution

    • Coitus or copulation is the process that leads to the release of semen from the penis into the vagina.
    • The sperms populate the vagina along with other contents of semen.
    • This process is called insemination.

  • Question 2
    1 / -0.25

    What part of the oviduct does the sperm encounter the egg?

    Solution

    • The egg is released and awaits in ampulla for the sperm.
    • The sperms cross the reproductive tract barriers before reaching the ampulla to fertilize the egg.

  • Question 3
    1 / -0.25

    What layer of egg cells prevents entry of other sperms?

    Solution

    The sperm contacts the egg cell at zona pellucida. The zona pellucida then undergoes chemical changes which renders the egg insusceptible to further encounters with another sperm. This is essential to ensure that only a single sperm fertilizes the egg.

  • Question 4
    1 / -0.25

    The haploid ovum is also called as _____________.

    Solution

    The haploid ovum is formed after the second round of meiosis is completed. This haploid ovum is also called ootid. Oogonium is the egg mother cell that is diploid and undergoes meiosis to form an egg.

  • Question 5
    1 / -0.25

    Ectopic pregnancy can occur in:

    Solution

    • Ectopic pregnancy occurs in regions other than the uterus.
    • An  ectopic pregnancy occurs  when a fertilized egg implants and grows outside the main cavity of the uterus. 
    • Most  ectopic pregnancies  (90%) occur  in  the fallopian tube , which are known as  tubal pregnancies , but implantation  can  also  occur  on  the cervix , ovaries, cesarean scar, or within  the abdomen .

  • Question 6
    1 / -0.25

    Enzyme for fertilization present in -

    Solution

    Acrosome of Sperm have enzymes for Sperm wall digestion.

  • Question 7
    1 / -0.25

    Location of fertilization is -

  • Question 8
    1 / -0.25

    What is the correct order of travel of sperm through the female reproductive tract before it reaches the egg?

    Solution

    Sperms are released into the vagina. From here, they travel through the cervix and uterus before reaching the  oviduct or fallopian tube, where they can encounter an egg.

  • Question 9
    1 / -0.25

    Number of meiosis II in female is Equal to -

    Solution

    Total no. of meiosis II is equal to total no. of fertilization.

  • Question 10
    1 / -0.25

    Which of the following is generally least in number?

    Solution

    Second polar body is the result of meiosis II occuring  after fertilization so it least in number.
