While doing a pedigree analysis of a royal family from the ancient Mayan empire, you notice that a prince with the genetic disease married a person from outside the royal family without a history of the disease in her family

Of their six children, two have the disease and four are
not affected. The prince's mother and his father also had this disease. If this disease is
controlled by a single gene, then the most likely explanation for disease in the children would
be:
A. the disease is a spontaneous mutation.
B. the disease is recessive and is only seen
in homozygous recessive individuals such as
the two affected children.
C. the disease is dominant and is only seen
in homozygous dominant individuals.
D. the disease is dominant and is seen in
heterozygous or homozygous dominant
individuals.
