Define Meiosis and Sexual Life Cycles.
Sexual reproduction Cell division and genetic variability-
Eukaryotic cells is able to divide by mitosis or meiosis. In humans mitosis produces fresh cells for growth and repair meiosis produces sex cells (gametes) called sperm as well as eggs.
Although mutations are the final source of genetic variability, both meiosis as well as sexual reproduction besides can contribute to new genetic combinations in offspring.
problem- How do both meiosis as well as sexual reproduction (fertilization) produce offspring that fluctuate genetically from the parents? Be sure to talk almost steps in meiosis that increase variability as well as the process of fertilization.
