medium
Fertilisation in humans is practically feasible only if
A
the ovum and sperms are transported simultaneously to ampullary-isthmic junction of the cervix
B
the sperms are transported into cervix within 48 hrs of release of ovum in uterus
C
the sperms are transported into vagina just after the release of ovum in Fallopian tube
D
the ovum and sperms are transported simultaneously to ampullary-isthmic junction of the Fallopian tube.
(NEET-2016)
Solution
(d) : The fusion of a haploid male gamete (sperm) and a haploid female gamete (ovum) to form a diploid zygote is called fertilisation. In human beings, it takes place in the ampullary isthmic junction of the oviduct (Fallopian tube).
