**Theme I: Understanding X-linked Recessive Inheritance of Red-Green Color Blindness**

To explore the inheritance pattern of red-green color blindness, consider the genetic information and potential phenotypes of the progeny provided in the scenario below:

**Scenario:**

- **Color Blind Father of Individual A** (X-linked recessive trait)
  
- **Individual A**: Prospective mother with normal color vision

- **Individual B**: Prospective father with normal color vision
  
**Question:** Which of the following four phenotypes is NOT expected among the progeny of Individuals A and B?

1. A color-blind chromosomal female
2. A color-blind chromosomal male
3. A non-color-blind chromosomal female
4. A non-color-blind chromosomal male

**Answer:** _______________ because _______________ 

**Conceptual Note:** In X-linked recessive inheritance, males are more likely to express the trait because they have a single X chromosome, while females require two copies of the recessive allele. Consideration of potential carrier status and gene combinations can help determine expected outcomes.

Expert Solution
Step 1: Explain

Since red-green color blindness is X-linked recessive trait, the color blind father of individual A would transfer the allele for color blindness to the individual A. Now, individual A is of normal vision because the recessive trait of the red-green is masked under the dominant trait. 

So in the given situation where an individual A with color-blind father has children with a normal vision male i.e. Individual B, the following might be  the results of the progeny:

  1. Normal vision female
  2. Normal vision male
  3. Color blind male
