How do I graph this problem on a punnet square?

### Genetics Cross Experiments 1. **Feather Color in Chickens** - **Concept**: Red feathers are dominant over white feathers. - **Task**: Cross a heterozygous red rooster with a homozygous white hen. - **Objective**: Determine the genotype and phenotype of the offspring. 2. **Plant Height in Peas** - **Concept**: Tall is dominant over short in peas. - **Task**: Cross a homozygous tall pea plant with a homozygous short pea plant. - **Objective**: Determine the genotype and phenotype of the offspring. 3. **Horn Length in Cows** - **Concept**: Long horns are dominant over short horns. - **Task**: Cross a homozygous long-horned bull with a homozygous long-horned cow. - **Objective**: Determine the genotype and phenotype of the offspring. ### Explanation: In each scenario, you will apply basic Mendelian genetics principles to predict the offspring's traits. The dominant trait is expressed with uppercase letters (e.g., R for red feathers, T for tall plants), and the recessive trait is in lowercase (e.g., r for white feathers, t for short plants). By setting up Punnett squares, you can calculate possible genetic outcomes.

**Genetics Practice Problems** 1. **Red feathers are dominant over white feathers in chickens.** - **Cross**: A heterozygous red rooster with a homozygous white hen. - **Task**: Give the genotype and phenotype of the offspring. 2. **Tall is dominant over short in peas.** - **Cross**: A homozygous tall pea with a homozygous short pea. - **Task**: Give the genotype and phenotype of the offspring. 3. **Long horns are dominant over short horns in cows.** - **Cross**: A homozygous long-horned bull with a homozygous long-horned cow. - **Task**: Give the genotype and phenotype of the offspring. **Diagram Explanation:** - There is a Punnett square labeled “1” to determine the possible genotypes of a cross: - Top row: B (allele 1), W (allele 2) - Left column: not labeled - Inner squares: - Top left: Bw - Top right: Ww - Bottom left: BB - Bottom right: Bw This Punnett square is used to calculate the possible genetic variations the offspring could inherit from their parents' alleles.
