a. Explain a monohybrid cross taking seed coat colour as a trait in Pisum Sativum. Work out the cross upto generation.
b. State the laws of inheritance that can be derived from such a cross.
c. How is the phenotypic ration of generation different in a dihybrid cross?
b. Law of Dominance : In a contrasting pair of factor one member of the pair dominates the other.
Law of Segregation : Factors or allele of pair segregate from each other so that a gamete receives only one of the two factors.
c. Phenotypic ratio of in monohybrid cross 3:1 whereas in a dihybrid cross the phenotypic ration is 9:3:3:1.
