Detailed explanation-1: -When a fertilized egg has implanted in the uterus, the group of cells that will become a baby is called an embryo. A developing, fertilized egg is known by several names within the first 2 weeks after conception, including zygote, morula (day 4), and blastocyst (day 5).

Detailed explanation-2: -A zygote, also known as a fertilized ovum or fertilized egg, is the union of a sperm cell and an egg cell. The zygote begins as a single cell but divides rapidly in the days following fertilization. The zygote’s single cell contains all of the 46 necessary chromosomes, getting 23 from the sperm and 23 from the egg.

Detailed explanation-3: -When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (ZYE-goat). The zygote goes through a process of becoming an embryo and developing into a fetus.

Detailed explanation-4: -Zygote: The fertilized egg is called as a zygote. Zygote is an initial stage in baby development. It is also known as fertilized ovum formed from the union of male and the egg cells.

Detailed explanation-5: -A cell that has two copies of each chromosome is referred to as a diploid. Hence, a Zygote is diploid. Each chromosome is present in two homologous, or comparable, copies in almost all human body cells. Due to the presence of both of its parents’ genes, the zygote is diploid (carrying two sets of chromosomes).
