The different forms a gene may have for a trait are called alleles. Blood type is an example of alleles. They determine the hereditary characteristics an offspring gains from their parents.
The cells show characteristics of tumors.
Tumor cells have the ability to grow and proliferate in absence of adhesion or anchoring. This is particularly helpful during metastasis when a cancer cell travels through the bloodstream to another location.

A cancerous cell has a number of mutations that regulate cell division. In addition, they exhibit impairment in DNA repair system. Therefore, cancer cell divided fast. Since the DNA repair system is nonfictional, the cells do not pause division to repair the mutation.</span>
