Question

if parents blood group is O positive, then what will be the child's blood group?

Answer 1

$\textbf{BONJOUR!!}$

✳ The blood group O appears when the gene for 'O' remains in homozygous condition. If the blood group of parent's is O+ then her blood group can also be O+ if it is recessive.
