CAN A+ and O have a child?

An A+ parent and an O+ parent can definitely have an O- child.

What blood type if parents are A and O?

ABO Blood Type Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.

Is it possible for a mother with type O blood and a father with type A to have a child with Type AB Why or why not?

Believe it or not, in this case having a blood type different from either parent is by far the most common result. In most cases, an O parent and an AB parent will have only A or B kids. It is only very rarely that they might have an AB or an O child (see the links at the end for these exceptions). Isn’t genetics fun!

Can parents with O blood have an a child?

Two O parents will get an O child nearly all of the time. But it is technically possible for two O-type parents to have a child with A or B blood, and maybe even AB (although this is really unlikely).

What if a mother is O+ and the father is O+?

A mother is O+ and the father is o+, what would the child be? Both parents have two genes for O type blood (we know this because O is recessive. If they had an A or B gene, they wouldn’t be type O). Both parents have at least one Rhesus + gene each.

Can the ABO blood type charts be used to predict paternity?

The ABO blood type charts below can be used to predict the possibilities of paternity. 1. The ABO blood type of the child when the blood type of the father and the mother are known (top chart), or 2. The ABO blood type of the father if the blood type of the child and the mother are known (bottom chart).

What blood type does a parent with a and AB have?

One parent with A and another with AB will give their child either A, B or AB groups. One parent with A and another with O will give their child either A or O blood group. It is second most popular and also one of the complex blood types discovered by Landsteiner and Weiner in 1940.

Is it possible for two positive parents to have a negative?

It is possible for two positives to have a negative child, simply stated you have not passed on the antigen to your child. However two negatives cannot have a positive child because the antigen is not present to pass on. Since the positive is dominant over negative it requires both parents to not pass on the antigen for the child to be negative.
