Given below is a list of events related to human reproduction: A. Release of secondary oocyte from the ovary B. Fusion of male and female pronuclei C. Extrusion of second polar body D. Sperm comes in contact with zona pellucida E. First cleavage division Choose the correct chronological sequence of these events.

Step-by-step solution

The correct sequence of events during human reproduction is as follows: First, ovulation occurs, which is the release of the secondary oocyte from the ovary (A). The oocyte reaches the fallopian tube where a sperm comes in contact with the zona pellucida layer of the ovum (D). This contact induces the completion of the meiotic division of the secondary oocyte, resulting in the extrusion of the second polar body and the formation of an ootid/ovum (C). Following this, the haploid nucleus of the sperm and that of the
