Oplození
Oplození, also known as fertilization, is the fusion of male and female gametes to initiate the development of a new individual. In sexual reproduction, this process involves the union of a sperm cell from the male with an ovum (egg cell) from the female. This fusion results in the formation of a zygote, a single diploid cell that contains genetic material from both parents.
The process typically occurs internally within the female reproductive tract, although external fertilization is common in
Following fertilization, the zygote undergoes a series of rapid cell divisions, a process called cleavage, as
