1. _________reproduction is a means of creating new individuals solely by________ the form of cell division that creates genetic
mixer [17]

Answer:

1. asexual, mitosis  2. sexual  3. gametes, meiosis  4. haploid 5. sex cells

Explanation:

Asexual reproduction is the form of reproduction that occurs whereby there is no fusion of gametes or a change in the number of chromosomes. The produced daughter cells are genetically similar to the parent. the form of cell division that occurs here is through a process of mitosis.

Different organisms adopt different type of asexual reproduction including binary fission, spore formation, fragmentation etc.

Sexual reproduction in contrast generates genetically unique organism through the fusion of two different organisms sex cells. To accomplish sexual reproduction, gametes that are haploid through a process of meiosis must be produced which are the egg cell and the sperm cells (the sex cells). These haploid cells are produced only in the germ cells to ensure the production of a diploid zygote.
