Blood Bank Set 1 Test Questions and
All Correct Answers 2025-2026
Updated.
Dominant - Answer trait expressed whether allele is homozygous or heterozygous
amorph - Answer recessive gene which produces no visible effect
dosage - Answer stronger agglutination when antibody is reacted with cells demonstrating
homozygous expression of antigen
genotype - Answer which genes a person has
homozygous - Answer allele at given point are the same (EE)
heterozygous - Answer alleles at given point are different (Ee)
locus - Answer position of gene on the chromosome
phenotype - Answer observable or testable effect of a gene
linked - Answer genes so close on chromosome that they are usually inherited together
recessive - Answer gene or trait expressed only if in homozygous form (such as sickle cell
anemia)
co-dominant - Answer heterozygous alleles both expressed (blood type AB)
sex-linked gene - Answer located on X chromosome
light chain - Answer inner short chain (on diagram)
heavy chain - Answer outer long chain (on diagram)
Fab portion - Answer upper section of heavy chain
