Answer:
Sam, Tim, Bella, and Joshua
Explanation:
The correct answer would be <em>Sam, Tim, Bella, and Joshua</em>.
<u>The human pedigree is a pictorial representation of a family tree that depicts how a particular trait is inherited across different generations.</u>
In the human pedigree, those phenotypically affected for the trait in question are represented by filled-in shapes, with circles representing females and squares representing males. Half-filled shapes represent heterozygosity or carriers of the trait.
<em>Sam, Tim, Bella, and Joshua were represented by filled-in shapes in the illustrated pedigree. Hence, they are affected for red-green color blindness. </em>
