Question
**E.** Through genetic analysis, we find that II-1 is actually heterozygous. Given this new information, what is the probability that his daughter (III-1) is heterozygous?

**F.** If we change the genotype of the grandfather (I-1) to AA, what is the probability that his granddaughter (III-1) is heterozygous? Continue to assume that II-1 is heterozygous.

**G.** Let’s go back to assuming that II-1 is AA. However, let’s continue to say that I-1 is also AA. What is the probability that III-1 is heterozygous?

The text is part of a genetics problem set discussing inheritance probabilities across generations. It focuses on determining the likelihood of a specific descendant (III-1) being heterozygous under different assumptions about the genotypes of their ancestors.

The pedigree chart displayed illustrates the inheritance pattern across three generations. Here's a detailed explanation of the chart:

**Generations:**
- The generations are marked on the left side with Roman numerals: I, II, and III indicating the first, second, and third generations, respectively.

**Individuals and Relationships:**
- Squares represent male individuals, and circles represent female individuals.
- Horizontal lines connecting a square and circle indicate a mating pair.
- Vertical lines lead to their offspring.

**Genotype Labels:**
- Individuals I-1 and I-2 are both marked with the genotype "Aa", suggesting they are heterozygous for a particular trait.

**Generation I:**
- I-1 (male) and I-2 (female) form a couple and both have the genotype "Aa".

**Generation II:**
- The couple I-1 and I-2 have four offspring: II-1 (male), II-2 (female), II-3 (male), and II-4 (male).
  
**Generation III:**
- Individual II-1 (male) and II-2 (female) have one child, III-1 (female).

This chart is a visual representation used in genetics to track the inheritance of specific traits through generations, particularly focusing on genetic variations and potential hereditary conditions within a family.
