d. Between implantation and parturition

Answers (1)

Ans: The answer is the option (a) between the zygote and blastocyst

Explanation: The haploid nuclei of the sperm and ovum fuse to form a diploid zygote. As the zygote travels through the isthmus of the oviduct toward the uterus, mitotic division, known as cleavage, begins, resulting in the formation of 2, 4, 8, and eventually 16 daughter cells called blastomeres. When the embryo consists of 8 to 16 blastomeres, it is referred to as a morula. The morula continues to divide and transforms into a blastocyst as it moves further along, eventually embedding itself in the endometrium of the uterus—a process known as implantation.
