White is controlled by the dominant allele, the recessive allele is purple. Therefore white would show in the heterozygous flowers, and purple would not.
Explanation:
The greenhouse effect works much the same way on Earth. Gases in the atmosphere, such as carbon dioxide, trap heat similar to the glass roof of a greenhouse. These heat-trapping gases are called greenhouse gases. ... At night, Earth's surface cools, releasing heat back into the air.
