This pedigree shows how a trait is passed on in a family. Males in the pedigree are shown with boxes and females are shown with circles. Individuals who have the trait are shown as darkened figures.

To determine which two individuals have the trait in the pedigree you mentioned, we need to look for the darkened figures representing those who express the trait. Since I cannot see the image, I can't provide a specific answer tailored to the pedigree you've described.

However, you can analyze the options based on the individuals shown in your pedigree:

• A. Two sisters: Look for two darkened circles that represent females.
• B. The father and the mother: Check if both individuals (a box and a circle) are darkened.
• C. The grandfather and a granddaughter: Look for a darkened box (the grandfather) and a darkened circle (the granddaughter).
• D. The grandmother and a grandson: Check for a darkened circle (the grandmother) and a darkened box (the grandson).

Whichever option corresponds to the individuals that are darkened in the pedigree indicates who has the trait.
