The time period between fertilisation and birth in mammals is termed as
Correct answer: A. Gestation
- A. Gestation
- B. Ovulation
- C. Conception
- D. Implantation
Explanation
The correct answer is gestation. Gestation is the period from fertilization until birth in mammals, where the embryo develops into a fetus. Ovulation is the process of releasing an egg, which precedes fertilization. Conception is the actual fertilization of the egg by the sperm, which marks the start of pregnancy. Implantation occurs when the fertilized egg attaches to the uterus, which is an early stage of pregnancy but not the entire period.
