Question

Quizplus · Accepted Answer

Monozygotic (identical) twins result from a single fertilized ovum splitting into two separate zygotes during early cell division, leading to two genetically identical embryos. It occurs by chance and is not influenced by family history, age, or other factors. Meiosis and fertilization involve the union of gametes and the creation of genetically unique offspring. Two ova being fertilized by different sperm would result in dizygotic (fraternal) twins. Mitosis is a process of cell division that occurs in somatic (body) cells and is involved in growth, tissue repair, and reproduction of asexually reproducing organisms.
