Question 8.
Amniocentesis for sex determination is banned in our country. Is this ban necessary ? Comment.
Amniocentesis is a method for sex determination of the foetus. Due to ethical and spiritual reasons, in India female foetus is not accepted and foetus is destroyed by some families.

Question 9.
Suggest some methods to assist infertile couples.
They are some Assisted Reproductive Technologies (ART) to assist infertile couples.
Some ARTs are:

  • Test tube baby / IVF-ET (Invitro fertilization and Embryo transfer) : Ova and sperms are collected and fused (induced) to form zygote in laboratory conditions and transferred into fallopian tube (ZIFT – Zygote intra fallopian transfer) or Uterus (IUT – Intra uterine transfer). Here male / female / both may be donor.
  • GIFT – (Gamete intra fallopian transfer). Gamete is from donor.
  • ICSI – (Intra Cytoplasmic sperm injection). Sperm is directly injected into the ovum.
  • AI (Artificial Insemination). Semen from husband ( AIH) or donor (AID) is injected directly into vagina or uterus (IUI – Intra uterine insemination)

2nd PUC Biology Reproductive Health Two Marks Questions

Question 1.
Amniocentesis for sex determination is banned in our country. Is this ban necessary ? Comment. [CBSE – 2006]
Since the amniocentesis is misused for female foeticide, the ban is necessary. But by banning this, its advantage of finding out any chromosomal disorders and / or metabolic disorders of the foetus is lost. So, it should be legalized with some strict conditions to avoid its misuse.

Question 2.
Why is hormone releasing IUD considered a good contraceptive to space children ? [CBSE – 2008]
Hormone releasing IUDs

  • Make the uterus unsuitable for implantation.
  • Make the cervix hostile to sperms.
  • Increase the phagocytosis of sperm within the uterus.

Question 3.
How does Cu T act as an effective contraceptive for human females.
Cu T is an intra – uterine device (IUD) and functions as follows:
The Cu ions released suppressed sperm motility and the fertilizing capacity of sperms.
IUDs increase phago cytosis of sperms with in the uterus.

Question 5.
Explain any 2 methods of Assisted reproductive Technology (ART) that has helped couples to bear children.

Question 4.
(a) What does gamete intra fallopian transfer (GIFT) represent ?
(b) How do Cu-T and Cu 7 acts as contraceptive devices ?
(a) GIFT – It is the introduction of 2 unfertilized oocytes and 2-5 lac motile sperm into fallopian tube of a woman desires to have a child through laparoscope. The egg may be of her’s or of a donor. The sperm may be her husband’s or of a donor. Fertilization occurs inside the fallopian tube and the development of foetus takes place through natural process.

(b) Cu-T, Cu 7 are intra uterine, contraceptive devices having ionized copper. The copper defuses into uterus. It brings about the release of toxic cytokinins. They inhibit the sperm motility and therefore  fertilization of ovum. Another categories of IUDs are hormonal in nature. (Eg: LNG – 20).
