During menstruation,

Question

Quizplus · Accepted Answer

Menstruation is the shedding of the thickened uterine lining, which occurs if no fertilized egg implants in the uterus. If fertilization does occur, the fertilized egg will implant in the uterine lining, and menstruation will not occur. Therefore, the unfertilized egg is discharged during menstruation. Choice A is incorrect because a female is actually more likely to get pregnant during ovulation, which occurs about 14 days before the start of menstruation. Choices C and D are incorrect because meiosis and mitosis occur during the early stages of embryonic development, not during menstruation.
