Answer 1

Some individuals with blood group B may inherit the genes for black hair, while other individuals with blood group B may inherit the genes for brown hair. This can be explained by the principle of independent assortment.

Explanation:

"If the inheritance of more than one pair of characters (two pairs or more) is studied simultaneously, the factors or genes for each pair of characters assort independently of the other pairs," says the law of independent assortment. The two allelomorphic pairs for characters - blood group and hair colour - are taken into account in the example above, which can be expressed in several ways.
