Question

Is a zygote alive?

Answer 1

A zygote is a eukaryotic cell created when two gametes fertilise each other. The genome of a zygote is made up of the DNA from each gamete and contains all of the genetic information required to produce a new organism.

Complete answer:
The union of an oocyte and a sperm produces this cell. A zygote is the embryonic stage of a human being (i.e., an embryo). A fertilised ovum is a secondary oocyte that has been impregnated by sperm and has become a zygote until fertilisation is full.

This new single-cell human being creates human-specific proteins and enzymes right away, and genetically controls his or her own growth and development. (In fact, it has been shown that the mother has little control over this genetic growth and development.) Finally, the single-cell human zygote is a biological individual, a living organism, and a special member of the human race.

In conclusion, mature human sperm and mature human oocytes are both gametogenesis products of just 23 chromosomes each. They each have half the number of chromosomes that a human being requires. They would not be able to transform into human beings on their own. Only "gamete" proteins and enzymes are produced by them. They are not in control of their own creation and growth. They aren't individuals, either, since they aren't members of the human race. They're all bits and pieces of a human being.

A human being, on the other hand, is the direct outcome of fertilisation. As a consequence, he or she is a single-cell embryonic zygote, an organism with 46 chromosomes, the minimum number for a human. This human being creates only human proteins and enzymes, guides his or her own growth and development as a human, and is a modern, genetically distinct, newly existing live human individual.

Note: The single-cell human embryo does not transform into anything else after fertilisation. It essentially separates and grows larger and larger, growing as an embryo over multiple stages over the course of eight weeks. A morula (about 4 days), a blastocyst (5-7 days), a bilaminar (two layer) embryo (during the second week), and a trilaminar (3-layer) embryo are some of the names given to these developmental stages of the developing embryo (during the third week).
