Answer 1

Solution

Given

Mr. Simpson has blood type ABRH+.( iA iB Rh+ )

Mrs. Simpson has blood type ORh+( ii Rh+ )

Crossing between them we get.

Mr Simpson. (iA iB Rh+) X. Mrs. Simpson(ii Rh+)

F1. iAi ( A+). iBi(B+). iAi (A+). iB(B+)

Simpson baby will be either A+ or B+

Mr.Doodly has blood type ARh- (iAiA or iA I Rh- )

Mrs Doodly has blood blood ORh+ (ii +)

Crossing between them we get

Mr Doodly ( iAiA - - ) x. Mrs Doodly ( ii+ -)

F1. iAi - iAi +. iAi- iAi+ ( All has A blood group)

They could not win the case since they have correct baby with them.
