Question

why are some pea plants tall and others short in nature?explain with references to the role of genes in controlling characteristics.

Answer 1

All the genes carry some specific codes, in this case they carry codes to produce proteins and enzymes. These proteins and enzymes control the height and other appearance of the plant. The higher production of these proteins helps the plant to grow more. and vice versa 

Answer 2

The reason for pea plants to be tall and short is explained below:

• The plant's acquired genes are mostly responsible for physical characteristics.
• A specific gene sequence determines qualities such as height, color, form, and other features.
• A certain collection of proteins or hormones regulates the characteristics of living organisms.
• The pea plant will grow taller if the gene sequence is such that it creates a hormone that impacts the height attribute.
• If the gene sequence is in such a way that this hormone is only produced in little amounts and is controlled by specific conditions, it will have no effect on height growth. It will be a short plant.
• As a result of the involvement of genes in influencing such phenotypic characteristics, some pea plants are tall and others are short in nature.
