for anyone good with biology ?

Question

okay heres my question ....

can a couple whos blood type is
Mom- O+
and
Dad- A+
have a child whose blood type is O-?

please help!!

Answer 1

If mom is O, that means her two genes are O and O.
If dad is A, that means his two genes can be A and A, or A and O.
There is a 50% chance that the child will get a O gene from mom, and a O gene from dad.
I forgot about the + and - though, sorry. It's been a year since I learned that stuff.

You should ask this in the Biology Section.
