WebA zygote is generally 1 cell with a Diploid (2 complete sets) set of DNA that came from the fusion of a moms haploid sex cell and dad’s haploid sex cell (each 1 cell with 1 complete set of DNA that fuses together to become 1 cell with 2 complete sets that is now unique) Then when the zygote grows from 1 cell into a full grown adult. WebFirst stages of segmentation of a mammalian embryo. Semidiagrammatic. z.p. Zona pellucida. p.gl. Polar bodies. a. Two-cell stage. b. Four-cell stage. c. Eight-cell stage. d, e. Morula stage. A polar body is a small haploid cell that is formed at the same time as an egg cell during oogenesis, but generally does not have the ability to be fertilized.
WebThe zygote develops by mitosis, and when it has developed into a compacted ball of 8-16 cells becomes known as the morula. Until this stage in development, all cells ( blastomeres) are autonomous and not specified to any particular subsequent functional development. WebDoes a zygote have DNA?

WebWe could thus imagine that the cells produced through meiotic division of the zygote, undergo mitosis, thereby developing into a multicellular organism. Since the term gamete is restricted to “haploid reproductive cells” a new term is needed for the cells derived from the zygote and developing into a gametophyte. These are called spores. A
