Explanation:
Detailed explanation-1: -PP – homozygous dominant – two copies of the dominant (purple) allele.
Detailed explanation-2: -Listen to pronunciation. (HEH-teh-roh-ZY-gus JEE-noh-tipe) The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).
Detailed explanation-3: -Because the allele for purple flowers (P) is dominant, only one P allele is needed for the plant to have purple flowers. A plant with two dominant or two recessive alleles is said to be homozygous (O moh ZIE guhs). A plant that has the genotype Pp is said to be heterozygous (HET uhr OH ZIE guhs).
