If False, change it. If mitosis makes somatic cells, what does meiosis make? Figure 8. 20/3 Instead, these cells assemble membrane proteins (in vesicles that bud off the Golgi apparatus) in their interior at right angles to the spindle apparatus. For example, human chromosome #19 contains a gene for eye color. The result is two genetically identical sister chromatids (However, do note that interphase is technically not a part of mitosis because it takes place between one mitotic phase and the next). Four haploid daughter cells are produced at the end, unlike two diploid daughter cells in mitosis. Situations in which one allele for a gene is not completely dominant over another allele for that gene are called Meiosis II is very similar to mitosis; chromatids are separated into separate nuclei. Concept note-4: This is a fun and interactive way to review the very important parts of the human life cycle. DNA.
