WebJan 17, 2024 · The phenotype is the actual physical features shown by the organism. In pea plants, like in the example above, if the dominant allele for purple flowers is present in the genotype, then the phenotype would be purple. Even if the genotype had one purple color allele and one recessive white color allele, the phenotype would still be a purple flower.
