Across between homozygous purple-flowered and homozygous white-flowered pea plants results in offspring with purple flowers. this demonstrates

Explanation:

Since the offsprings all exhibited purple phenotypic characteristics, It shows that in the gene coding for colour in the flower of the pea plant, the allele for purple colour is dominant over the allele for white colour.

It further shows, according to the law segregation, that the gametes produced by the purple and white peas are dominant and recessive respectively. This Indicates that the parent purple-flowered pea is homozygous dominant (PP) while the parent white-flowered pea is homozygous recessive (pp), hence all the offsprings will be heterozygous dominant (Pp).
