sexual in this kind of reproduction, genetic material is donated from 2 parents asexual in this kind of reproduction genetic material is donated from only 1 parent variation different combinations of alleles lead to ________ in offspring identical in asexual reproduction, offspring are ________ to the parent and each other environment with change in _______, for sexual reproduction: some may die but others may survive; for asexual reproduction, all may die. individuals in asexual reproduction _______ can reproduce without mates, it is fast and independent of outside forces vegetative reproduction where an individual grows new from parts of parent (from stems, leaves, roots) binaryfission reproduction where parent divides into 2 identical organisms binaryfission reproduction used by flatworms, bacteria, amoebas budding exact copy grows from parent’s body budding reproductions used by Hydra cloning artificial duplication of one parent mitosis During ______ the cell nucleus divides into 2 nuclei, and then the cell divides. mitosis During ______ 1 parent cell becomes 2 complete daughter cells, with complete set of chromosomes development in ulticellular organisms, mitosis helps with growth and _______ and replacing dead cells unicellular in _______ organisms, mitosis is for reproduction meiosis in this process, a second division of genetic material produces the sex cells meiosis in this process, 1 parent cell becomes 4 daughter cells chromosomes in meiosis, each daughter cell has half the _______ of the parent chromosomes after union of 2 sex cells (1 from each parent) the new individual will have the full number of ______ necessary to survive variation Genetic ______ is helps ensure survival ~~~~~~~~~~~ sexual asexual variation identical environment individuals Vegetative binaryfission budding cloning Mitosis development Unicellular meiosis chromosomes
