GENERAL HISTOLOGY

Detailed explanation-1: -Fertilization and completion of meiosis. (A) Fertilization induces the transition from metaphase II to anaphase II, leading to completion of oocyte meiosis and emission of a second polar body (which usually degenerates).

Detailed explanation-2: -Answer and Explanation: Fertilization does not actually occur during meiosis at all, but is a separate process. Meiosis is the process by which sperm are produced in the male and eggs are produced in the female. Fertilization occurs using the end products of meiosis, but it is not part of the process itself.

Detailed explanation-3: -Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes (sperm and eggs). However, sexual reproduction includes fertilization (the fusion between gametes), which is not part of the meiotic process.

Detailed explanation-4: -Hence meiosis should occur before fertilization to maintain the number of chromosomes in the zygote and prevent chromosomal defects in the offspring.

Detailed explanation-5: -Meiosis is a process that takes place in the ovaries of females during the development of mature gametes or eggs. Meiosis II completes only if fertilization occurs.
