Question

The human zygote gets implanted in the
A. Fallopian tube
B. Ovary
C. Urethra
D. Uterus

Answer 1

Hint: It is also called a womb and it is a hollow muscular organ of the female reproductive system which is located between the bladder and the rectum.

Complete answer:
The zygote is the first diploid cell that forms following fertilization by the fusion of the haploid(egg) and sperm resulting in the combination of their separate genomes.
The zygote then forms a conceptus which is the embryonic cellular products of fertilization. The zygote stage of development in humans occurs during the first day in week one following the fertilization and this stage is described as the Carnegie stage 1.
The stage 1 is followed by mitosis to form two blastomeres and then a solid mass which is called morula. The fertilized egg which zygote moves towards the uterus and implant in the uterine wall where it will reside and complete the course of nine months.
So, from the discussion it is clear that human zygote gets implanted in the uterus where it resides for 9 months.

Thus, the correct answer is option D. i.e., Uterus

Additional information:
Fallopian tubes are also called uterine tubes of the female reproductive parts that transport ova from the ovary to the uterus each month. The ovary is the part of the female reproductive organ that produces an ovum. Urethra is a thin fibromuscular part whose purpose is to conduct urine from the bladder to the outside of the body.

Note: Various disorders may take place due to the defect in the fertilization process. One of the defects is polyspermy which results from multiple sperm fertilizing an egg. It is possible in some species like vertebrates and it is a lethal condition for human zygotes.
