Question

in this pedigree, which family members are carriers of a recessive trait? * 1 point
o both parents
o mother only
o second and fourth offspring
o first and second offspring

Explanation:

Carriers of a recessive trait have one dominant and one recessive allele. In a pedigree, when two unaffected parents have an affected offspring (showing the recessive trait), the parents must be carriers. Here, the parents are unaffected but have an affected child, so they are carriers.

both parents
