Which statement summarizes the law of segregation

The statement which  summarizes the law of segregation is as follows :  

During the process of gamete formation, two different forms of a gene ( also called allele) segregate from one another in a random manner and each gamete thus formed, receives one copy of gene.

This is called the law of segregation. It was proposed by Gregor Mendel.  

For example- The gene for plant height in pea exists in two forms which are T ( dominant allele- represents tall height ) and t ( recessive allele- represents dwarf height ). If a plant is heterozygous ( having different alleles Tt), it will give two different gametes ( T and t ) during gametogenesis.  

These alleles are segregated in accordance with the law of segregation.
