Study Notes
Fertilization and Zygote Formation
- Fertilization results in the formation of a zygote, which is a unicellular organism that forms when a sperm fertilizes an egg.
- A zygote is typically described as a diploid cell (2n) containing genetic material from both parents, combining one set of chromosomes from each gamete.
- Terms like "blastocyst" or "embryo" do not refer directly to the zygote stage but rather to subsequent stages of development after fertilization.
Role and Characteristics of the Zygote
- The primary role of a zygote in reproduction is to undergo cleavage and development, ultimately leading to the formation of a multicellular organism through mitotic divisions.
- A false statement regarding the zygote might suggest that it does not have the potential to develop into an organism, which contrasts with its actual capability.
