Question

PLEASE HELP ASAP!!!! A pedigree chart is a diagram that shows how members of a family are related to one another.

It may also show which members of a family express a certain genetic trait.
In a pedigree chart, females are represented by circles and males are represented by squares. A
horizontal line between a male and a female indicates a couple with offspring, and a vertical
line connects the couple to their child or children. Siblings are denoted by branches off the
vertical line. Each separate generation is represented by a Roman numeral.
An example of a pedigree chart is shown below.

Answer 1

A. D and F

Step-by-step explanation:

A pedigree chart tracks a trait throughout family history. However, when people are added into the tree due to marriage, they don't share the same DNA as the family. So, we can see that the person labelled "F" was married into the family since they don't have any lines connecting to them. "H" and "J" are the children of "F", so they are related and so is the wife, "E", but nobody else is genetically related to "F".
