There is an accumulation of genetic mutations in the DNA of sperms due to its constant mitosis.
Explanation:
The germinative cells that will become sperms are under constant mitosis. During this process, DNA mutations can happen and be transmitted from one generation of cells to the other as the years go by, and more cell divisions take place, more mutations the DNA in the sperm will have. When the number of mutations reaches a certain level, his child will express these mutations and have autism.
The egg of the mother is not a factor because the germinative cells in women are not under constant mitosis, so there is not an accumulation of gene mutations. Women are born with an exact number of eggs for all their life.

The nosepiece rotates to easily change the magnification. It holds two or more objective lenses that hold different degrees of augmentation power. This allows the person using the microscope to locate and detect different objects using a lower power lens and then examine the objects more closely with the high power one. There would only be one level of magnification if it didn't have a nosepeice .
