**Genetics - Understanding Dominant and Recessive Traits in Purple People Eaters**

**Problem 4:**
In purple people eaters, one horn (H) is a dominant trait, and no horns (h) is a recessive trait. You are asked to cross a hybrid purple people eater (one with genotype Hh) with a purple people eater with no horns (genotype hh).

**Diagram Explanation:**
The diagram below the problem statement represents a Punnett square, a tool used in genetics to predict the genotype and phenotype of offspring from a cross between two organisms. The Punnett square is divided into four boxes to show the possible combinations of alleles from the parents.

**Genotype Calculation:**
To determine the possible genotypes of the offspring, we fill in the Punnett square with the alleles of the parents. The hybrid parent has the genotype Hh (one dominant allele H and one recessive allele h), and the no-horn parent has the genotype hh (two recessive alleles):

|    | h | h  |
|----|---|----|
|**H**| Hh | Hh |
|**h** | hh | hh |

From this Punnett square:
- There are two boxes with the genotype Hh.
- There are two boxes with the genotype hh.

**Genotype Results:**
- **Hh:** 50% of the offspring will have one horn.
- **hh:** 50% of the offspring will have no horns.

**Phenotype Calculation:**
Phenotype refers to the organism's observable traits, resulting from the genotype.

- The Hh genotype will show the dominant trait: one horn.
- The hh genotype will show the recessive trait: no horns.

**Phenotype Results:**
- 50% of the offspring will have one horn.
- 50% of the offspring will have no horns.

**Conclusion:**
From crossing a hybrid purple people eater with a purple people eater with no horns, the offspring will have a 50% chance of having one horn and a 50% chance of having no horns.
