During meiosis II, the two daughter cells are split further into 4 distinct haploid cells, each with a single set of 23 chromosomes. During meiosis I, a normal cell splits and results in the formation of two daughter nuclei. Sperm and eggs contain half of a complete human genetic code and will fuse their chromosomes to create a diploid zygote. In humans, the haploid gametes are sperm and eggs. ![]() Meiosis is similar to mitosis in that both involve cellular division, but is different in two fundamental ways: Mitosis creates two genetically identical cells each with a full set of chromosomes while meiosis shuffle the genes in the chromosomes to create haploid cells genetically distinct from the parent cell and produces cells with half the normal number of chromosomes. Meiosis itself is divided into 2 major phases, meiosis I and meiosis II, each divided into 4 sub-phases, prophase, metaphase, anaphase, and telophase. “Life is the division of human cells, a process which begins at conception.” - Dick Gephardt ![]() In humans, a normal body cell has 46 chromosomes (2 sets of 23), so a human gamete only has 23 chromosomes. Unlike mitosis, which is the normal process of cell division, the haploid cells created by meiosis, called gametes, have half the normal number of chromosomes. Meiosis is an important part of sexual reproduction in eukaryotes as it provides the raw genetic materials that combine to create a diploid zygote. Meiosis refers to the process by which a single diploid cell divides into 4 haploid cells, each genetically distinct from the parent cell.
