LAW OF SEGREGATION
This law was proposed on the basis of monohybrid experiments.
According to this law, ”Even though the recessive allele remains masked by the dominant allele and fails to manifest its phenotype in the f1 generation, up on selfing of the f1 generation during gametogenesis the recessive allele segregates without being affected by the dominant allele.” This results in the expression of recessive allele in f2 generation. So, it is also called as “Law of purity of gametes”.
Dwarf character exhibited.
Phenotype ratio of f2 generation is 3 : 1 (tall : dwarf).
Genotype ratio of f2 generation is 1 : 2 : 1.
