Identical Twins DNA

The DNA patterns for identification in identical twins has caused great havoc in our society. DNA (deoxyribonucleic acid) is the genetic material of life that encodes the genetic instructions used in the development and functioning of all known living organisms. Identical twins (monozygotic) are formed when one fertilized egg develops into two eggs. Fraternal twins (dizygotic) are formed when two separate sperm fertilize two separate eggs. (Mader and Windelspecht, 2014).

There are some actors that contribute to the production of twins. Some women are more likely to have twins than others. Women that have higher levels of estrogen like those between the ages 30 to 40 are more likely, because they produce more than one egg at a time which increases the chances of multiple fertilizations from sperm to egg. The more pregnancies or births that a mother has had also increases the chances of twins. A woman that is a twin, siblings are twins or come from the mother of a twin is more likely to have twins herself. One would think that race would not be a factor in a woman having twins, but in fact a black African woman has the highest rate of having twins while an Asian woman has the lowest rate of having twins. Finally a woman can increase her chances of having twins by using technology. Technology allows for the opportunity to stimulate the ovaries, so that they will increase the number of eggs being released. This procedures increases the chances of having multiple births. (Twins –Identical and Fraternal)
When the egg is fertilized during its journey down the fallopian tube it attaches itself to lining of the womb and thereby begins the dividing and evolution of the embryo. Identical twins (monozygotic) genetic or DNA makeup is the same, because they come from the same cell. This cell will have the same maternal and paternal genetic makeup meaning they will be from the same mother and father. Fraternal twins (dizygotic) genetic or DNA can...
