A pea plant has purple flowers. It has a genotype PP. Which of the following about the gene of flower color in the pea plant is true? The pea plant has only recessive alleles for the gene. The pea plant received the same allele from each parent. The pea plant received different alleles from both parents. The pea plant has both recessive and dominant alleles for the gene.

The pea plant received the same allele from each parent. PP means homozygous dominant.

The correct answer is option (B) the pea plant received the same allele from each parent.Allele can be defined as the two alternative forms of a gene occupying the same locus on a chromosome. A dominant allele is the one which expresses itself even with one copy of the allele and produces a phenotype. An organism is said to be homozygous dominant if it carries two copies of the same dominant allele. A purple plant with the genotype PP is said to be homozygous dominant. An offspring recieves two alleles from each of the parent. In a homozygous dominant purple pea plant, dominant alleles of the parents are recieved by the offspring and the genotype becomes PP.
