(a) Explain the statement that color blindness is perfect example for criss -cross inheritance with a flowchart.

Explanation

A marriage between a colour blind man and a normal visioned women will produce normal visioned male and female individuals in `F_(1)` generation but the females are carries. The marriage between a `F_(1)` normal visioned carrier women and a normal visioned male will produce one normal visioned female, one carrier female, one normal visioned male and one colour blind male. Colour blind trait is inherited from the male parent to his grandson through carrier daughter, which is an example of criss-cross pattern of inheritance.
