What is the cycle of birth?

The cycle of birth refers to the biological process through which new life is created and developed. It typically begins with fertilization, where a sperm cell merges with an egg, leading to the formation of a zygote. This zygote undergoes multiple divisions and differentiations, eventually developing into an embryo and then a fetus, culminating in childbirth. This cycle is fundamental to the continuation of species and is influenced by various environmental, genetic, and maternal factors.
