Study Notes
Gamete Formation
- The process resulting in gamete formation is called meiosis, a type of cell division that reduces the chromosome number by half.
- Meiosis produces four non-identical haploid cells, crucial for sexual reproduction.
Fertilization Process
- Upon fertilization, the ovum (egg) is joined by a sperm, forming a single cell called a zygote.
- This process restores the diploid chromosome number, combining genetic material from both parents.
Chromosome Counts
- Gamete cells, which are haploid, contain 23 chromosomes in humans.
- The zygote, as a diploid cell, contains 46 chromosomes, inheriting 23 from each parent.
Zygote Development
- The defined development process that the zygote undergoes is known as embryogenesis.
- This period involves rapid cell division and differentiation, leading to the formation of tissues and organs as the embryo develops.
