Answer:
The correct answer is - segregation.
Explanation:
The law of segregation states that out of two factors or alleles of a gene located in an organism, only one allele or factor is distributed to each sperm cell or egg cell (gamete) randomly, So, the segregation of the alleles are random and only one allele is distributed to each gamete according to this law.
The law of segregation helps in making a different combination of alleles in a particular species or population and leads to variation in genetics. It makes sure that traits distribute to each generation randomly.

Answer:
The teeth in the mouth bite off a piece of food. 
The teeth continue to break the food into smaller pieces.
Saliva rushes into the mouth and mixes with the broken-down food.
The food travels down the esophagus.
The muscles of the stomach churn the food and continue to break it down.
The broken-down food, called chyme, enters the small intestine.
The remaining food passes into the large intestine. Water is absorbed from the large intestine and the rest of
the material is stored as solid waste until it is excreted from the body.
