Twins develop from two separate fertilized eggs and share percent of their genes.

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:

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.

Factor that increase increase the probability of twins are :

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.
