Answer:
Meiosis is a process in which sex cells, also known as gametes are made. Meiosis is different from mitosis in a lot of ways, one being that mitosis creates identical daughter cells and meiosis creates unique daughter cells. Meiosis is important because it allow for the creation of a meiosis nucleus. Cells produced by meiosis will be used in haploid, where each member of the next generation is genetically unique.
Cells produced in <u>sexual reproduction</u> will have half of the genetic information of body cells and will be genetically <u>unique</u>. This is necessary because when a sperm and an egg fuse together in sexual reproduction. They form a <u>zygote</u>: the first body of a new individual.
The new individual will now have cells that are <u>diploid</u>, meaning they have two sets of chromosomes. They zygote will have to do a lot of <u>mitosis</u> allowing it to grow quickly and ensure that all of its cells are genetically unique.
