In which of the following techniques, haploid cell is transferred into the fallopian tube?
In GIFT (gamete intra fallopian transfer), ovum is transferred into the fallopian tube of a female who cannot produce an ova. Ovum is a haploid cell.
In ZIFT(zygote intra fallopian transfer), a zygote or embryo upto 8 blastomeres is transferred into the fallopian tube.
In IUT (intra uterine transfer), an embryo with more than 8 blastomeres is transferred into the uterus.
Zygote and blastomeres are diploid cells.
In IUI (intra-uterine insemination), semen is artificially introduced into the vagina or uterus. Semen has sperms which are haploid cells but these are not transferred into the fallopian tube.
Hence the correct answer is GIFT.
