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

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

Solution :

Correct option : C 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 ‘.
