• A. the product of in-vitro fertilisation followed by implantation of embryo in the female.
• B. the one which is reared in an artificial environment outside the womb.
• C. formed inside the fallopian tube.
• D. formed through the technique of artificial insemination.

Answer 1

The correct option is A the product of in-vitro fertilisation followed by implantation of embryo in the female.

Test tube baby is formed through the technique of IVF followed by ET.

In IVF (in vitro fertilisation), ova from the female and sperms from the male are collected and induced to form zygote in the laboratory.

The zygote or early embryo (with upto 8 blastomeres) is then transferred into the fallopian tube or the embryo with more than 8 blastomeres is transferred into the uterus.
This is called embryo transfer (ET).

Further development takes place inside the body of the female.
