Examples of asexually reproducing species include bacteria (binary fission), plants (runners, bulbs), and some animals (parthenogenesis). Offspring inherit genetic material from a single parent, lacking genetic variation.
Asexual reproduction involves the creation of offspring without the union of gametes. It results in genetically identical or nearly identical offspring to the parent, common in plants, bacteria, and fungi.
Chromosomes are thread-like structures in cells containing DNA. They carry genetic information, determining an organism’s traits. Humans have 23 pairs, with one set inherited from each parent.
Male gamete (sperm) is small, mobile, and contributes genetic material. Female gamete (egg) is larger, non-motile, and provides nutrients. Fusion during fertilization forms a zygote, initiating development.
