Read the following statements.
(i) Birth control pills are likely to cause cardiovascular problems.
(ii) A woman who substitutes or takes the place -of the real mother to nurse the embryo is called surrogate mother.
(iii) Numerous children have been produced by in vitro fertilisation but with some abnormalities.
(iv) Woman plays a key role in the continuity of the family and human species.
(v) Foetal sex determination test should not be banned.
Which of the following pair consists of incorrect statement ?

  1. (i) and (ii)

  2. (ii) and (iv)

  3. (iii) and (v)

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Numerous children have been produced by in vitro fertilisation without any abnormality. Foetal sex determination test should be banned as it is being misused for female foeticide.

Which of the following breeding techniques is used to improve herd genetics?

  1. Artificial insemination

  2. Embryo transfer

  3. Both A and B

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Both the methods are used to improve the herd genetics by adding a new set of desired genes to the herd. This increases the quality of the gene pool of the herd.  

So the correct option is 'Both A & B'.

Transfer of ovum from donor to recipient oviduct is

  1. GIFT

  2. ICSI

  3. ZIFT

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

GIFT referred as a gamete intra Fallopian transfer. In this, the egg from the donor and the sperm from the father (or the donor male) is taken and are transferred to the oviduct or the Fallopian tube of the recipient. 

So the correct option is 'GIFT'.

Stage transferred to uterus after induced fertilization of ova in the laboratory is

  1. Embryo at two-blastomere stage

  2. Morula

  3. Zygote

  4. Embryo at four blastomere stage
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In Intra-Uterine Transfer (IUT) embryo with more than 8-blastomeres stage (morula) is used for transfer into the uterus after induced fertilisation in the laboaratory.

So, the correct answer is 'Morula'.

Assisted reproductive technology, IVF involves transfer of

  1. Zygote into fallopian tube

  2. Zygote into uterus

  3. Embryo with 16 blastomeres into the fallopian tube

  4. Ovum into fallopian tube
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In vitro fertilization is a method in which fertilization of male gamete (spermatozoon) and female gamete (ovum) outside the body in almost similar conditions as that in the body followed by zygote or embryo transfer(ET). The zygote or early embryo(upto 8 blastomeres stage) then transferred to fallopian tube called zygote intra fallopian transfer or ZIFT. So, the correct answer is 'Zygote into fallopian tube'.

Embryo with more than 16 blastomere formed due to in vitro fertilization is transferred into

  1. Cervix

  2. Uterus

  3. Fallopian tube

  4. Fimbriae
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The zygote or early embryo (upto 8 blastomeres stage) is transferred to fallopian tube called zygote intra fallopian transfer or ZIFT. IUT (Intrauterine transfer), the embryo with more than 8 blastomeres is transferred into the uterus. So, the correct answer is 'Uterus'.

Consider the following statements.
In vitro micro propagation has the advantages of.
a. Range of variability
b. Year round availability
c. Small size of explants
d. Production of disease free prop gules.
Which of the statements given are correct?

  1. $1, 2$ and $4$ only
  2. $2, 3$ and $4$ only
  3. $1$ and $3$ only
  4. $1, 2, 3$ and $4$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In vitro micropropagation allows for year-round production, the use of very small explants, and the generation of disease-free plants. Variability is generally avoided in micropropagation as it aims for clonal uniformity.

Which one of the following technique has been widely used to overcome sexual incompatibility?

  1. In vitro fertilization

  2. Geitonogamy

  3. Allogamy

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

In vitro fertilization (IVF) or embryo rescue techniques are widely used in plant breeding to overcome sexual incompatibility barriers that prevent fertilization in vivo.

In vitro fertilisation is a technique that involves transfer of which one of the following into the Fallopian tube?

  1. Embryo only, upto $8$ cell stage
  2. Either zygote or early embryo upto $8$ cell stage
  3. Embryo of $32$ cell stage

  4. Zygote only
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

ZIFT ( Zygote Intrafallopian transfer) is a technique in which oocyte and sperms are taken and fertilization takes place outside the female's body i.e. in vitro. Early embryo with more than 8 blastomeres is transferred to the fallopian tube.

So the correct option is ' Either zygote or early embryo upto 8 cell stage '.
