Rasek [7]

Answer:

C: If crossed with another heterozygous plant, the majority of progeny will have the dominant flower color.

Explanation:

Assuming the gene is represented an allele A, purple colour can be AA or Aa while white colour will be aa.

If a heterozygous plant Aa is crossed with another heterozygous Aa, the genotype of the progeny will be AA, Aa, Aa and aa.

Since allele A is dominant over a, it thus means that the phenotype of the progeny will be 3 purple and 1 white flowered plant.

<em>Hence, the majority of the progeny will have the dominant (75%) flower colour.</em>

The correct option is C.
