ZIFT is

Options

A. transfer of zygote into the Fallopian tube
B. transfer of embryo into the uterus
C. transfer of mixture of sperms and ova into the Fallopian tube
D. transfer of mixture of sperms and ova into the uterus

Answer

**Step-by-Step Solution:**

1. **Understanding ZIFT**: ZIFT stands for Zygote Intra Fallopian Transfer. It is a type of assisted reproductive technology (ART) used to treat infertility.

2. **Purpose of ZIFT**: ZIFT is utilized in cases where the fallopian tubes are blocked or unable to provide a suitable environment for fertilization. This means that natural fertilization (the fusion of sperm and egg) cannot occur.

3. **Process of ZIFT**: In ZIFT, after fertilization occurs (which can happen through in vitro fertilization), the resulting zygote is directly transferred into the fallopian tube of the female reproductive tract.

4. **Evaluating Options**:
- **Option A**: Transfer of zygote into the fallopian tube - This is correct as it directly describes the ZIFT procedure.
- **Option B**: Transfer of embryo into the uterus - This describes a different procedure known as Embryo Transfer (ET), which follows in vitro fertilization (IVF).
- **Option C**: Transfer of a mixture of sperms and ova into the fallopian tube - This is incorrect as ZIFT involves the transfer of a zygote, not a mixture of gametes.
- **Option D**: Transfer of a mixture of sperms and ova into the uterus - This is also incorrect for the same reason as Option C.

5. **Conclusion**: The correct answer is that ZIFT is the transfer of the zygote into the fallopian tube.

**Final Answer**: ZIFT is the transfer of zygote into the fallopian tube.
