Question

how do genes control the characteristics of tallness of a plant​

Answer 1

The genes control the characteristics of tallness of a plant​

Explanation:

• A gene is the section of DNA on a chromosome which codes for the formation of a protein controlling a specific characteristic (or trait) of the organism.
• Suppose a plant progeny has gene for the characteristic called ‘tallness’. Now, the gene for tallness will give instructions to the plant cells to make a lot of plant growth hormones.
• And due to the formation of excess of plant growth hormones, the plant will grow much and hence become tall.
• On the other hand, if the plant has the gene set for dwarfness, then less plant growth hormones will be produced due to which the plant will grow less, remain short and hence become a dwarf plant.
