Explanation:

(a)The embryo gets nourishment inside the mother's body through the placenta. It is a unique disc organ that occurs in the fourth week of fertilization.

(b) The blood group of the mother is O, which means it has genotype ii.

Her father's blood group is A, meaning he can have the I^{A}I^{A}  or I ^{A} i genotype.

Case i) - If the genotype of father's blood group isI^{A} I^{A}and mothers is ii.

In this case, the girl has type A blood.

Case ii) - If the genotype of father's blood group is I^{A} i and mothers is ii

At this case, the girl is 50% more likely to have blood type A and 50% more likely to have blood type O.

Case i) and Case ii) is explained clearly in the given attachment.
