Question at position 86 By which cell division process does an animal zygote divide?meiosismitosis

Question

BlackTom AI · Accepted Answer

The question asks about the cell division process by which an animal zygote divides, and presents two options: meiosis or mitosis.
Option: meiosis. In animals, meiosis is the type of cell division that produces gametes (sperm and egg) with half the chromosome number. It occurs during gametogenesis before fertilization, not after a zygote is formed. Therefore, the zygote does not repeatedly undergo meiosis as part of its early development. 
Option: mitosis. After fertilization, the zygote is a diploid cell that begins to divide through mitosis as it undergoes embryonic development. Mitosis produces genetically identical diploid daughter cells, allowing the single fertilized egg to grow into an embryo through successive rounds of cell division. 
In summary, meiosis is the division that creates gametes prior to fertilization, while mitosis is the division that drives post-fertilization embryonic development in animals. Therefore, the animal zygote divides by mitosis, not meiosis.
