heridity and evolution

Law of segregation of characters and purity of gametes - The factors controlling a particular trait separate or segregate from one each other during gamete formation. Each gamete has only one of a pair of contrasting characters. So the gamete is pure for a particular trait.

 

 Law of independent assortment - In crossing over, if 2 or more traits are involved (say height and colour), their factors i.e. genes assort independently, irrespective of the combinations present in the parents.  Each one of the pair of contrasting characters will coexist with either of another paired type.
