Dizygotic twins develops from two separate fertilized eggs and share 50 percent of their genes.

Further Explanation:

Genotypes help in the genetic makeup of any individual.Phenotype describes as a physical characteristic of an individual. Genotype responsible for the phenotypes of any individual.

Twins are of two types:

Monozygotic
Dizygotic

In monozygotic twins only one egg and sperm fertilized and form identical twins.In this fertilized egg divide into two parts and they have same genetic makup .They share 100% similar gene.

In dizygotic twins two eggs released in one cycle and fertilized with two sperm.They form dizygotic or fraternal twins. They share 50% of smiliarities between gene and they are like sibling born at different time.

The body determines whether certain genes should be expressed or not. Sometimes genes are only turned on once or twice in a life

zmey [24]

The gene which is produced once or twice in a lifetime is the milk producing hormone after childbirth. This is because it is produced only after the birth of the child. The growth of the mammary glands takes place during pregnancy. The breast continue to increase in size after giving birth to a child. After delivery only copious milk is produced which is generally done with the help of milk hormone. During pregnancy the secretion of the milk is inhibited by the estrogen and progesterone which circulates in the blood stream which in turn inhibits the release of prolactin from the pituitary gland thus making the mammary glands unresponsive. Where as insulin is a hormone which helps the body to utilise the sugar or glucose from different sources like carbohydrates that we get while we eat food and adrenaline is secreted when we are scared or when we feel that we are in danger. Therefore, milk producing hormone is the gene that are turned once or twice in a lifetime.
