Answer:
Mendel's law of dominance
Explanation:
A pea plant homozygous for purple flowers could have the genotype PP. A pea plant homozygous for white flowers could then have the genotype pp.
This means that all the offpsring have the genotype Pp, see the attached punnet square.
Because the P allele is dominant to the p allele, the plants have purple flowers. This is in agreement with Mendel's law of dominance. This states that for a dominant trait (following a cross of two different homozygous genotypes), hybrid offspring of the next generation will always express the dominant allele.
