Question

discuss how gene heterometry, heyerochrony, or heterotopy may have impacted a particular plant structure and development?

Answer 1

Answer-

Heterometry- In this condition the amount of expression of some genes changes during developmental processes which leads to the difference in amount of protein product. This difference in amount of protein will lead to some developmental changes.

This leads to quantitative changed in plant body which are correlated with number is flowers or inflorescences.

Heterochrony- In this condition the genetic variance leads to two difference in duration of developmental processes as compared to their ancestors. This leads to change in size, shape or even presence of certain organs in plant body.

It may lead to deformation in shape of plant body.

Heterotopy- This condition is characterized by a change in spatial positioning of some process in the embryo, which can also create morphological innovation.

This may lead to abnormal position of roots or abnormal pattern of branching.
