Question

what do we call individuals that are \half - shaded\?
normal
afflicted
carriers

Explanation:

In a pedigree chart, half - shaded individuals are typically carriers. Carriers have one normal allele and one recessive allele for a particular trait (usually a genetic disorder). They do not show the symptoms of the disorder (unlike fully - shaded 'afflicted' individuals) and are not 'normal' (who have two normal alleles).

Answer:

Carriers
