Easy summary of Mendel’s law


Mendel’s law:  
Gregor Mendel describes the inheritance of traits passed from one generation to the next.
The mendel‘s law has three parts: 

1.      The Law of Dominance

Mendel's law of dominance states that one gene (dominant gene) is dominant or powerful can mask the expression of other gene (recessive gene).  
Single dominant gene can express the character
Two dose of recessive genes can express the character  

2.      The Law of Segregation

Mendel's second law, the law of segregation, states that two alleles of a gene segregated or separated during formation of gametes.  
So one copy of parent gene  only pass  to their offspring for a particular trait .
 Offspring gets second copy of gene from another parent. 
These  segregation or separation occur during meiosis. 

3.      The Law of Independent Assortment

 During gamete formation alleles of genes located on different chromosomes are assorted or distributed independently. The transmission of one character does not influence the transmission of other character.
