Genotype - Wikipedia
网页There are three available genotypes, PP (homozygous dominant), Pp (heterozygous), and pp (homozygous recessive). All three have different genotypes but the first two have the same phenotype (purple) as distinct from the third (white). A more technical example to illustrate genotype is the single-nucleotide polymorphism or SNP.
