Question

ASSERTION: Transfer of an ovum collected from a donor into the Fallopian tube of another female who cannot produce an ovum, is called GIFT.
REASON: Transfer of early embryos with up to 8 blastomeres into the Fallopian tube of the female, is called ZIFT.
A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
C. Assertion is correct but Reason is incorrect.
D. Both Assertion and Reason are incorrect.

Answer 1

Hint: In GIFT the gametes (each egg and sperm) are then injected into the fallopian tubes using a surgical operation known as laparoscope. The doctor will use usual anesthesia. Whilst in ZIFT, fertile eggs are implanted inside the uterus and become a fetus via the same process.

Complete answer:
To answer this question, first, we need to know about gamete and zygote intrafallopian transfer. Some infertile couples are influenced by a situation that saves the sperm and egg from moving through a fallopian tube.
Gamete intrafallopian transfer (GIFT) makes use of more than one egg amassed from the ovaries. The eggs are located into a skinny bendy tube (catheter) along with the sperm to be used.Zygote intrafallopian transfer (ZIFT) combines in vitro fertilization (IVF) and GIFT. Eggs are triggered and acquired using IVF methods. Then the eggs are combined with sperm inside the lab. Fertilized eggs (zygotes) are then laparoscopically backed to the fallopian tubes in which they will be carried into the uterus. The aim is for the zygote to implant inside the uterus and become into a fetus.Now, let us find the solution from the option.
Gamete Intrafallopian transfer is a method used for the women that cannot produce an ovum however can give an appropriate surrounding for the foetus to grow.
In such situations, the ovum from the donor women is transplanted into the fallopian tube of the women. Zygote intrafallopian transfer is a technique that is done after the fusion of male and female gametes in vitro. Here, the zygote up to eight blastomeres stage is transplanted into the fallopian tube.

Hence, the correct answer is option(B)

Note: GIFT changed into usually performed within the past, especially for females who desired to do IVF however keep away from the conception exterior of the body. The eggs are triggered and harvested much like in IVF, but the eggs and sperm are placed into the fallopian tube where fertilization happens. ZIFT is likewise just like IVF however entails transfer of the fertilized egg (the zygote) into the fallopian tube on the time of laparoscopy. In the past, like GIFT, ZIFT had a higher pregnancy rate than IVF. With the arrival of stepped forward embryo transfer strategies and advanced laboratories, ZIFT has additionally grown to be obsolete.
