Gestation period- The time interval of a gestation is called the gestation period.
Zygote- A zygote is a eukaryotic cell formed by a fertilization event between two gametes.
Parturition is the process of the contraction of the uterus at regular intervals that results in the delivery of the baby at the end of pregnancy.
The signals that the fully developed fetus sends through the placenta for ejection is called Fetal ejection reflex.
These signals induce muscular contractions.
A zygote is a eukaryotic cell formed by a fertilization event between two gametes.
The zygote's genome is a combination of the DNA in each gamete, and contains all of the genetic information necessary to build a new individual. In multi cellular organisms, the zygote is the earliest developmental stage.
Semen, also known as seminal fluid, is an organic fluid that may contain spermatozoa.
It is secreted by the gonads (sexual glands) and other sexual organs of male or hermaphroditic animals and can fertilize female ova.
Gestation period: Fetal development period from the time of conception until birth.
For humans, the full gestation period is normally 9 months.
