Question

the Mendelian principle which can be
derived from a dihybrid cross and not from
monohybrid cross.


​

Answer 1

• Third law of the Mendel or Law of the Independent Assortment can be derived from the Dihybrid cross and not from the monohybrid cross.
• Monohybrid cross can be only use to derive the Law of Dominance and Law of the Segregation. (First and second law)
• Law of Independent Assortment of the Mendel says that, '' The Law of Independent Assortment is a principle of inheritance that states that each heritable allele (contrasting pair of gene) is inherited independently of one another. ''

Phenotype ratio = 9 : 3 : 3 : 1

Genotype Ratio = 4 : 2 : 2 : 1 : 1 : 2 : 1 : 2 : 1
