Since the moon was most likely broken off from earth, it lacks this central heat. @Kb0812 Hope this helps and if your feeling generous feel free to leave a rate, thanks and brainliest because it would really help me reach expert and I would appreciate it ;)</span></span>
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.
