a single gene controls flower color in peas. the purple flower allele is dominant to the white flower allele. if you cross a heterozygous purple-flowered plant with a white-flowered plant, the resulting offspring will have a phenotypic ratio of:

Answer :

The phenotypic ratio of a heterozygous purple-flowered plant crossing with a white-flowered plant will be 75% purple: 25% white because the purple flower allele is dominant over the white flower allele.

A dominant allele determines the color of white blooms. A recessive gene determines whether blossoms appear purple. Alleles that are dominant are represented by capital letters, and alleles that are recessive are represented by lowercase variations of the same letters. Purple flower color predominates over white blossom color in the pea plant. Self-pollinating plants are those that cross pure purple flowering plants with white flowering plants.
