Mendel's Laws of Heredity

 

Law Of Dominance:

     According to it a pair of factors present in the born offspring one factor comes through the male while another comes through the female.  In these factors the character of one factor is suppressed by the character of another and the suppressing factor is called dominant character, while other factor if called recessive character.  In the first generation only the dominant character is visible, while recessive character is hidden and it appears in the next generation.

Monohybrid cross

Law of Segregation:

     According to this law during the gametes formation the factors of pairs of factors become segregated and out of these factors only one factor is reached in the gamete.  Both the factors never come at a time in the gamete.  This law is also called as Law of purity of gametes.

Law of Independent assortment:

     According to this law various pair of the factors (genes) which exist in any organism are independent to each other and may unite arbitrarily to any other.  Thus the organism of new appearance may be born.

Dihybrid Cross
