Answer:
True
Explanation:
Hello!
In the human body, meiosis is the process by which specialized cells divide to form gametes (ovum in women and sperm in men).
Through the meiosis process, four haploid cells are obtained from a diploid cell. Haploid cells are those that have only one set of chromosomes.
In women, only one of the four haploid cells formed keeps all the organelles of the stem cell acquiring a large size (ovum).
In fertilization, a haploid sperm fertilizes a haploid egg giving rise to the zygote (diploid) that will give rise to a new aoganism.
When meiosis is not completed correctly the gamete may contain a duplicate (2 copies) of one or more chromosomes, in this case fertilization normally occurs but may give rise to:
-An unviable zygote.
-A viable zygote with a genetic disease due to a trisomy of one of its chromosomes (Dawn syndrome is an example with the trisomy of chromosome XXI).
