Meiosis is important to eukaryotes, such as plants, animals and fungi, because it is the method by which they produce sex cells. The ability to produce sex cells, and therefore reproduce sexually, increases the genetic diversity of the population. This increased genetic diversity provides a greater pallet of mutations on which natural selection can act.Know More
While most cells in eukaryotes divide through mitosis, sex cells, called gametes, divide by using a different process, termed meiosis. In mitosis, each daughter cell contains the full genetic compliment that was in the parent cell. By contrast, daughter cells that follow meiosis only have half of the genetic code of the parent cell. In other words, sperm and egg cells feature one-half of the DNA it takes to make an organism. When the male and female sex cells combine and initiate fertilization, the cells each contribute half of the DNA for the daughter organism.
Sexual reproduction is common among most macro-organisms, although some plants also use asexual methods of reproduction, such as vegetative propagation. Additionally, some animals, notably sponges, anemones and jellyfish, reproduce asexually by a process known as budding. In each of these examples, the offspring are genetically identical to the parent organisms.Learn more about Cells
Arizona State University states that meiosis is how sexually reproducing organisms, including humans, produce gametes, or sex cells. Gametes are fundamentally different from the body, or somatic, cells of sexually reproductive organisms because gametes only have half of the genetic code in their nucleus. When two different gametes fuse and produce a zygote, their half-complements of genetic material combine to form a complete genome with the full complement of chromosomes.Full Answer >
Meiosis is a cell division process that occurs twice to produce four haploid daughter cells, according to Biology4Kids. Meiosis I occurs first and creates two daughter cells, and then meiosis II begins and creates two more daughter cells.Full Answer >
Meiosis is the process of cell division that creates offspring in sexually reproducing organisms, explains a University of Illinois at Chicago website. Unlike during mitosis, meiotic cell division starts with double the number of chromosomes in diploid parent cells. Meiosis cuts this number in half forming two haploid daughter cells. When these daughter cells combine and undergo fertilization, a zygote is created and the cell begins to develop.Full Answer >
Meiosis is the process in which cells divide to produce sex cells. Meiosis takes a single cell and divides it into four different cells with half of the necessary chromosomes for human development. Meiosis creates both egg and sperm cells.Full Answer >
