Question

in pea plants, purple flowers are dominant to white flowers. list all the possible genotypes for a purple flower.(write the homozygous genotype first, then the heterozygous genotype use the letter p for the alleles).

Explanation:

Step1: Understand dominant - recessive alleles

Dominant allele (P) masks recessive (p). Purple is dominant.

Step2: Determine homozygous genotype

Homozygous dominant has two dominant alleles: PP.

Step3: Determine heterozygous genotype

Heterozygous has one dominant and one recessive allele: Pp.

Answer:

PP, Pp
