Is a test that can be used to detect genetic abnormalities before birth.

Amniocentesis

Explanation: Amniocentesis, a medical technique used to test DNA in amniotic fluid, allows physicians to identify genetic abnormalities before birth. A woman may choose to terminate a pregnancy rather than give birth to a child who will be born with serious birth defects. This presents a host of ethical questions:

* Do fetuses have rights?

* Is it ethical to abort fetuses?

* Is it ethical to abort fetuses because parents want to raise healthy children only?

* Is it ethical to abort fetuses that will suffer from lifelong, serious, and perhaps painful defects?

* Is it ethical for states to pass laws restricting women’s rights to abort pregnancies?...PF

In human blood types two alleles are inherited ,one from each parent.
If the allele is i it is a recessive trait.
Blood types possible: A, B, AB, O.

D. Is wrong because you don't inherit three alleles and there is more than just one outcome possible.
C. Is wrong because i is recessive and IA and IB are both dominate.
B. Is wrong because IA and IB are not codominant.

A. Is right because two alleles from parents. Alleles do code for blood types. and their are four phenotypes possible: A, B, AB, and O blood types.
