PRELAB EXPERIMENT 5: INHERITANCE

What is phenotype?

• The genetic makeup of an organism.

• The process of evolution in species.

• The set of observable characteristics of an organism.

• The study of ecosystems and their interactions.

What is genotype?

• The physical appearance of an organism.

• The environment in which an organism lives.

• A type of species classification.

• The genetic makeup of an organism.

Why human with heterozygous genotype will have the dominant phenotype?

• Heterozygous individuals can only express recessive traits.
• The dominant allele is always expressed regardless of the genotype.
• The dominant allele masks the effect of the recessive allele.

• A heterozygous genotype results in a completely recessive phenotype.

What are the THREE alleles that control the human ABO blood group?

• I^A

• I^B

• i

• I^O

What is the role of antibodies in blood typing?

• To transport oxygen in the blood.

• To initiate blood clotting.

• To bind to specific antigens on red blood cells.

• To regulate blood pressure.

Match the possible genotypes for the following phenotypes.

• I^Ai

• Blood group A

• I^AI^B

• Blood group B

• ii

• Blood group O

• I^BI^B

• Blood group AB

What does agglutination mean?

• The process of dissolving substances.

• The separation of particles in a solution.

• The formation of gas bubbles in liquids.

• The clumping of particles, often due to antibody binding.

When testing for blood group, what is the blood group if the blood agglutinates in an antiserum containing anti-A antibodies but not in an antiserum containing anti-B antibodies?

• Blood group A

• Blood group B

• Blood group O

• Blood group AB

If a person is selected randomly from the group above, what is the probability that his/her blood type is not O?

• 0.70

• 0.71

• 0.72

• 0.73
