Some plants are able to suspend their growth and development for a period of time in order to survive during harsh environmental conditions. once environmental conditions improve, these plants begin to grow and develop again. this suspension of plant growth is known as

Dormancy

Dormancy is a characteristic of plants to survive under adverse conditions by restricting or stopping their growth and development. The dormancy occurs in different organs such as seeds and buds of plants. It is controlled and regulated by genetic and environmental factors. Dormancy is because of  adaptive traits that favors the survival of the plants in unfavorable conditions. Dormancy allows plants to preserve their nutrients and energy by stopping their life processes and they can restart their life processes in favorable conditions by utilizing the stored nutrients and energy.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
