Sample A has a mutation affecting the cyclin-dependent kinases causing the cells to become cancerous.
Sample B has become cancerous and all cells are all dying off as the cancer spreads.
Sample C cells are unable to perform mitosis due to a mutation in the cells regulating proteins.
Sample D has a mutation preventing the s-phase of the cell cycle which then causes the number of cells to first increase then decrease.

Mendel's Law of Dominance states that dominant alleles must separate from recessive alleles in gamete formation.
Mendel's Law of Inheritance states that only one allele is inherited from each parent and the dominant allele is inherited first.
Mendel's Law of Segregation states that alleles must segregate during gamete formation in order to create haploid sex cells need for reproduction.
Mendel's Law of Independent Assortment states that each trait is inherited separately and the resulting gametes each only contain the DNA for a single trait.
When are sister chromatids produced?
DNA replication during the S phase of the cell cycle
Growth during G2 of the cell cycle
DNA replication during the M phase of the cell cycle
