Question

According to "evo-devo" thinking, an organism's body form can be substantially changed

A. through mutations or changes in the expression of one or a few genes that regulate development.
B. only through multiple mutations that produce a large number of new proteins.
C. through mutations that change sexually selected traits.
D. only when changes in the environment directly alter the major protein-coding genes in the organism's genome.

Answer 1

According to evo-devo thinking, an organism's body form can be substantially changed through mutations or changes in the expression of specific genes that regulate development. Option A

Step-by-step explanation:

The correct answer to the question is A. through mutations or changes in the expression of one or a few genes that regulate development.

According to "evo-devo" thinking, an organism's body form can be substantially changed through mutations or changes in the expression of specific genes that are involved in the regulation of development.

These mutations can result in significant variations in body form and structure, leading to the evolution of new traits and adaptations.

For example, changes in the expression of homeobox genes, which are involved in the regulation of body development, can have profound effects on the morphology and organization of body parts.

Mutations in these genes can result in the formation of completely new structures or changes in existing structures, leading to the evolution of different body forms. Option A.
