A hydrangea plant has blue flowers when grown in acidic soil, but has pink flowers when grown in basic soil. A clone of the pink-flowered plant is grown in acidic soil and produces blue flowers. This change in flower color is most likely due to:
a. sexual reproduction in the plants
b. resulting in variationasexual reproduction in the plants
c. resulting in variationgenes being expressed in different ways due to environmental conditions
d. a gene mutation that occurred after the clone was produced

Option C, resulting in variation genes being expressed in different ways due to environmental conditions

Explanation:

Several genetic traits are affected by both internal and external environmental conditions. Some common examples are – height , color of eye, hair color, skin color, and even some genetic diseases.  

The internal environmental factors include – gender, temperature etc.

While the external environmental factors include drugs, chemicals, temperature, and light.  

Hence, the external environmental condition i.e pH of soil is producing different color of flowers in a given plant

Hence, option C is correct

is this a question? wassup
