Question

The fertilized ovum is transplanted in uterus after

• A. 1 day
• B. 7 days
• C. 8 days
• D. 10 days

Answer 1

The correct option is B 7 days

• The fertilization takes place by the fusion of the male and female gamete. This fertilized egg undergoes cleavage and forms the blastocyst.
• The fertilized egg to reach the blastocyst stage takes around 6-7 days. The zygote at the blastocyst stage gets implanted in the wall of the uterus after about 7 days of fertilization.
  

Thus, the correct answer is option B.
