Question : Describe the cross between a homozygous tall round seeded pea plant and a dwarf wrinkled seeded pea plant, what will be types of propency in the F_(2)generation of thiscrossand in what proportion will it be ? Name and state the law which is explained by this example.

Answer»

Solution :If we represent the GENE for tall habit of pea plant with T and roundseed by R,then the genotype of tall round seeded pea plant will be TTRR.Similarly the genotypeof dwarfwrinkledseeded peaplantwill the ttrr.


`F_(2)`progeny : Tall round = 9
Tall wrinkled = 3
Dwarfround = 3
Dwarf wrinkled = 1
Phenotypic ratio = 9: 3: 3: 1
NAME of law = Law of independent ASSORTMENT
Statementof law = The law of independentassortment
