If a person is a carrier of a certain allele, they can pass on the allele
but do not show the trait in their phenotype. For example, a carrier of
hemophilia will not exhibit the disease, but he or she can pass the
disease allele to his or her offspring. We would say that a carrier is...
A. homozygous dominant
B. heterozygous
C. homozygous recessive
D. monozygotic
