Concordance = presence of the same trait.
Identical twins have a higher rate than fraternal because most of their DNA is identical, it’s identical because the zygote split into two so the babies shared an amniotic sack. (Zygote is fertilized egg) so the baby got duplicated meaning only one egg and sperm created two babies. Fraternal twins happen when two eggs are fertilized and grow in separate amniotic sacks. So two different babies, two different eggs and sperm.

chubhunter [2.5K]

Answer:

The correct answer is C. be more likely to have cancer at some point in his/her life.

Explanation:

Cell cycle checkpoints are controlled by different proteins which are coded by different genes. They are important in cell cycle regulation and stops cell cycle immediately if they find any problem in the cell like mutation.

The cell cycle will not be continued if the problem does not solve and cell death will occur which prevents cancer by preventing the mutation to spread into new cells.  

Therefore if a mutation occurs in certain genes that enforce a checkpoint on the cell cycle then the mutated gene will pass in new cells and the mutated cells will grow uncontrollably due to no checkpoints so the person will probably have cancer at some point in his or her life.
