lyudmila [28]

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>

Sorry if I am not right :(
I hope I helped you have a great day :)
