Zigóta

A zygote is the initial cell formed when two gamete cells fuse during sexual reproduction. Typically, this involves the fusion of a sperm cell and an egg cell. The zygote contains the complete genetic material from both parents, representing the beginning of a new, genetically distinct organism. Following its formation, the zygote undergoes a series of rapid cell divisions known as cleavage. These divisions lead to the formation of a multicellular structure that will eventually develop into an embryo. The zygote stage is a critical phase in development, as it marks the transition from single-celled reproductive units to a complex, developing organism. The process of zygote formation and subsequent development is fundamental to the life cycle of most eukaryotic organisms, including humans, animals, and plants. The genetic contribution from each parent within the zygote determines the inherited traits of the offspring.
