Answer
If R = Red and r = White

Which genotypes would result in a Red phenotype
Answered by GPT-4o mini
In this scenario, where R (Red) is dominant and r (White) is recessive, a White phenotype would only be observed in individuals with the genotype that contains two recessive alleles, which is:

- **rr**

The genotypes that result in a Red phenotype would include:

- **RR** (homozygous dominant)
- **Rr** (heterozygous)

The genotype **RrRr** is not a valid genetic designation in traditional Mendelian genetics.

So, the only genotype from your list that results in a White phenotype is:

- **rr**

In this scenario, where R (Red) is dominant and r (White) is recessive, the genotypes that would result in a Red phenotype are:

1. **RR** (homozygous dominant)
2. **Rr** (heterozygous)

Both of these genotypes will express the Red phenotype due to the presence of at least one dominant allele (R). Therefore, the genotypes that result in a Red phenotype are:

- **RR**
- **Rr**
