A developing embryo is typically more susceptible to damage/injury during the early stages of pregnancy.
This is an example of an Epigenetic effect.
Explanation:
It is the study of heritable changes in the expression of genes, that are not involved in the changes present in DNA sequence. It is regular and naturally occurred, sometimes factors are responsible like age, lifestyle and disease state.
At times it leads to more damaging effect that can cause cancer. So this is also related to various fatal disease. During adulthood epigenetic effect remains stable. It does not occur in mother womb, but during the lifespan. This epigenetic effect can be reversed.
Natural selection only occurs when there is a superiority within a species set. If there is no genetic variation, no single animal is any better than the next, making the presence of superiority impossible and survival left up to chance. In this case it would be considered genetic continuity.

Mitosis is the the white cells that recover our skin injury like a cut and mitosis cancer is the thing that can't be controlled and is bad for that body and people get this type of cancer of heredity of family passed down and a single cell replicating more trait of the damaging cell.
