- BTransfer of a zygote or early embryo with up to 8 blastomeres into the fallopian tube.
- CTransfer of embryos with more than 8 blastomeres into the fallopian tube.
- DTransfer of an unfertilized ovum collected from a donor into the fallopian tube.
Correct answer
B. Transfer of a zygote or early embryo with up to 8 blastomeres into the fallopian tube.
Step-by-step solution
ZIFT stands for Zygote Intra Fallopian Transfer. According to NCERT, in this procedure, the zygote or early embryos with up to 8 blastomeres are transferred into the fallopian tube to complete their further development. Embryos with more than 8 blastomeres are transferred into the uterus, which is called Intra Uterine Transfer (IUT). Transfer of an unfertilized ovum into the fallopian tube is known as Gamete Intra Fallopian Transfer (GIFT). Answer: Transfer of a zygote or early embryo with up to 8 blastomeres into
