NEET · Biology · STD 12 - 2. human reproduction
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.
Answer & Solution
Correct Answer
(D) the ovum and sperms are transported simultaneously to ampullary-isthmic junction of the Fallopian tube.
Step-by-step Solution
Detailed explanation
(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).
