In humans, aniridia, a type of blindness, is due to a dominant allele A. Migraine headaches are due to another dominant allele M. If a man who suffers from both conditions (AaMm) marries a woman who suffers from both (AaMm) , what are the chances of an offspring expressing both traits?
A) 9/16
B) 3/16
C) 1/2
D) 1/16
E) 4/16
AaMm
Represents a genotype consisting of two different alleles, Aa, for one trait and two different alleles, Mm, for another trait, indicating a hybrid individual.
Dominant Allele
An allele that expresses its phenotype even in the presence of a different (recessive) allele at the same genetic locus in a heterozygote.
Aniridia
A congenital condition characterized by the complete or partial absence of the iris, affecting the individual's vision.
