Front

What is the Rh factor in blood types?

Back

The Rh factor is a protein that can be present (+) or absent (-) on the surface of red blood cells.

Front

Front

What is the significance of antibodies in blood types?

Back

Antibodies in plasma can react with specific antigens on red blood cells, determining compatibility for blood transfusions.

Front

What is the genotype for blood type O?

Back

ii (homozygous recessive)

Front

How can blood type inheritance be predicted?

Back

Using Punnett squares to analyze the alleles from both parents.

Front

What is the role of multiple alleles in blood type variation?

Back

Multiple alleles allow for more than two phenotypes, as seen in the ABO blood group system.

Front

What happens during an incompatible blood transfusion?

Back

The recipient's antibodies attack the donor's red blood cells, leading to agglutination and potential health risks.

Front

What is the difference between blood type A and blood type B?

Back

Blood type A has A antigens and anti-B antibodies; blood type B has B antigens and anti-A antibodies.

Front

What is the importance of knowing a person's blood type in forensics?
