Biology

• Gametes


  Sex cells, such as sperm and egg cells, that contain half the number of chromosomes as the parent cell
• Meiosis


  Type of cell division that reduces the number of chromosomes by half, resulting in four daughter cells with genetic variation
• Fertilization


  Process by which a sperm cell fuses with an egg cell, resulting in the formation of a zygote with a complete set of chromosomes
• Oogenesis


  The process by which an ovum (egg cell) forms in the female reproductive system
• Spermatogenesis


  The process by which sperm cells form in the male reproductive system
• Meiosis I


  First stage of meiosis, where homologous chromosomes come together, exchange genetic information, and separate
• Meiosis II


  Second stage of meiosis, where sister chromatids separate and end up in different daughter cells
• Zygotogenesis


  Process by which the zygote begins to divide and develop into an embryo
