The answer is recessive alleles. Generally, a recessive allele
is the form of a gene that codes for a non-functional protein. When an individual inherits
recessive allele for a gene from both parents, then they are more likely to
suffer a disorder that is attributed to lack of the respective functional protein. Often the heterozygous individual will
not bear the disorder even though they carry
the recessive allele. This is because the
dominant allele is able to mask the
recessive allele by producing a functional
protein.
