Blood Types and Their Importance in Donation

The video explains phenotypes, focusing on blood types and their antigens. It covers blood type compatibility, the role of the immune system, and the importance of matching blood types for donations. The video also introduces the Rh factor and genetic inheritance, using a hypothetical problem to demonstrate blood type problem-solving with Punnett squares.

Which of the following is NOT a visible phenotype?

• Height

• Hair texture

• Eye color

• Blood type

What is the main reason blood types need to be matched during donation?

• To ensure compatibility of plasma

• To prevent clotting

• To match platelet count

• To avoid immune system attacks

Which blood type is considered the universal donor?

• Type O

• Type AB

• Type B

• Type A

Why can individuals with type AB blood receive blood from any type?

• They have no antigens

• They have both A and B antigens

• They have only B antigens

• They have only A antigens

What does a positive Rh factor indicate?

• Presence of A antigens

• Presence of B antigens

• Presence of Rh protein

• Absence of Rh protein

What is the genetic term for different forms of a gene?

• Genotypes

• Alleles

• Phenotypes

• Chromosomes

In the hospital mix-up scenario, what is the blood type of baby Phil?

• Type O

• Type AB

• Type B

• Type A

What is the genotype of a person with type O blood?

• ii

• IAIB

• IBIB

• IAIA

If both parents have type A blood, which genotype combination could result in a type O child?

• Both parents homozygous

• One parent homozygous, one heterozygous

• Both parents heterozygous

• One parent type A, one type B

What is the probability of a couple with heterozygous type A blood having a type O child?

• 0%

• 25%

• 75%

• 50%
