Question

now, answer the following questions:
a. which person is the son-in-law?
b. to whom is he married?
c. what is the gender of their child?

Explanation:

Part A: Identify Son - in - law

Step 1: Understand Family Tree Symbols

In a pedigree (family tree), squares represent males and circles represent females. A horizontal line between a square and a circle represents a marriage. A son - in - law is a male who is married to someone's daughter.

Step 2: Analyze the Family Tree

Looking at the tree, Generation I has I - 1 (male, black square) and I - 2 (female, white circle). Their daughter is II - 2 (female, black circle). The male married to II - 2 is II - 1 (white square). So II - 1 is the son - in - law.

Part B: Identify Spouse

Step 1: Locate the Son - in - law

We identified the son - in - law as II - 1.

Step 2: Find His Spouse

The horizontal line connects II - 1 (male) to II - 2 (female), so he is married to II - 2.

Part C: Identify Child's Gender

Step 1: Locate the Couple's Child

The couple (II - 1 and II - 2) has a child in Generation III, which is III - 1.

Step 2: Determine Gender from Symbol

In the pedigree, III - 1 is represented by a circle, which stands for a female.

Answer:

A. II - 1 (the white square in Generation II, number 1)
B. II - 2 (the black circle in Generation II, number 2)
C. Female
