Heredity is the process of passing of traits from one generation to the next generation. Now, this process would not lead to any interesting results (and in turn, the astonishing variety of life on earth), if this process was 100% accurate or faithful. So, even though traits are transferred from parents to their off-springs, the traits are usually marginally altered.
This gives rise to off-springs who are like their parents but with very minor changes. These changes could either be a) beneficial b) harmful (deleterious) or c) neutral.
Harmful changes cause the organism to perish before it can pass on these changes to the next generation. Sometimes a trait that existed in the earlier might become deleterious due to a change in the environment and thus, undergo the process of elimination from the population.
Beneficial changes help the organism to adapt better to its surroundings and live longer and have more off-springs such that these changes are spread to more and more organisms in the population and are eventually get fixed.
A series of such changes in a subsection of a population eventually lead to a new species which is nothing like the older generation. This process of “fixing” or beneficial changes and removal of deleterious traits from a population is called evolution.
Interestingly, the changes that seem the most inconsequential, the neutral changes, are responsible for the bulk of evolution. Neutral changes along with geographical isolation lead to a process called genetic drift, which is considered by many to be the strongest driving force of evolution.

What is Mitosis?
"Mitosis is the cycle that eukaryotic cells go through in order to divide. During mitosis, a cell duplicates its DNA and divides into two genetically identical cells.
Mitosis and cytokinesis are part of the mitotic phase of the cell cycle, which make up about 20 percent of the entire lifecycle of a cell. The end result of mitosis is two completely separate cells with equal and similar cellular components. "
"Meiosis is the special cell division cycle for gamete cells, or sex cells. Chromosomes carry the genetic code for an organism, and come in pairs. In asexual reproduction, a cell will just divide itself to create two new cells. In sexual reproduction, the parent provides one set of each chromosome, or half the genetic code for an organism. When the two parent donor gametes – typically an egg and sperm – meet in fertilization, they provide the offspring with the full set of necessary chromosomes. For example, humans require 46 chromosomes, or 23 pairs. An egg or sperm will have just 23 chromosomes, or one half of the pair. This makes gamete cell division more complex than ordinary cell division. Within this cycle, the number of chromosomes is halved, typically going from a diploid (two sets) to haploid (one set) cell. It also includes a step where the chromosomes cross, allowing for more genetic diversity in reproduction."

Hopefully that helped, have a wonderful day :)
The release of Follicle Stimulating Hormone (FSH) encourages sustentocytes to release androgen-binding protein (ABP). ABP causes the spermatogonia to bind testosterone. <span>Testosterone stimulates spermatogenesis. Hope this answers the question. Have a nice day.</span>
