In human fertilization, two 1n haploid cellsâan ovum (female gamete) and a sperm cell (male gamete)âcombine to form a single 2n diploid cell called the zygote.NA is then replicated in the two separate pronuclei derived from the sperm and ovum, making the zygote's chromosome number temporarily 4n diploid. After approximately 30 hours, fusion of the pronuclei and subsequent mitotic division produce two 2n diploid daughter cells called blastomeres.
It is called a morula, and consists of the first 16 cells from the division of the zygote (fertilized egg). The individual undifferentiated cells are known as blastomeres, and â¦ form a hollow structure called a blastocyst.Once differentiation of cells occurs, the structure is simply called an embryo, and later a fetus.t is called a morula, and consists of the first 16 cells from the division of the zygote (fertilized egg).
