Question

How are known carriers of a trait represented in a pedigree chart?

पर्याय

• Shapes with diagonal lines

• Fully shaded shapes

• Outlined shapes with a dot in the center

• Half-shading or half-filled shapes

Answer 1

Known carriers are represented using half-shading or half-filled shapes in a pedigree chart. This notation is particularly important for autosomal recessive traits and X-linked recessive traits, where heterozygous individuals may not show the phenotype but can pass the allele to their offspring.
