The three ‘laws of inheritance’ such as the law of dominance, the law of segregation and law of independent assortment are known as Mendelism.
● Law of independent assortment can explain by a dihybrid cross. In a dihybrid cross, two plants having two or more contrasting characters such as characters for example height of a plant and shape of a seed, are crossed then inheritance of one character is unaffected by inheritance of another character.
● In F2 generation formation of plants like dwarf plant with yellow seed and tall plants with green seeds, show an independent assortment of characters.
● Example: let’s observe the cross between a tall plant with round seeds (TTYY) and a dwarf plant with wrinkled seeds (ttyy). Tall plant with round seed is dominant characters.
Four types of plants are appeared in the F2 generation
