Question Detail
Question
Which of the following is a post-fertilization event in mammals? a. ovulation b. menstruation c. cleavage d. oogenesis
Correct Answer
Option C is the correct answer.
Detailed Explanation
Cleavage is the rapid series of mitotic cell divisions that the zygote undergoes after fertilization, resulting in a multicellular structure called a morula, then a blastocyst. Ovulation and oogenesis occur before fertilization. Menstruation is part of the cycle if fertilization does not occur.
Hint
It's the first thing the zygote does: divide without growing.
