Answer

Question 4

A) 25% chances of having a child with O blood group . Ie; Out of 4 children one will have O blood group

B) AB blood group- 25%

B blood group- 25%

A blood group- 25%

O blood group- 25%

(25% means 1 out 4 child have Particular blood group)

Explanation please find from the below attachment

couple blood group A and B. pannet square, O Fathers blood group BABOB АВ ов o ao fool Mothers blood group parents AOX BO o
