<span>Some of the more common single-gene disorders include cystic fibrosis, hemochromatosis, Tay-Sachs, and sickle cell anemia.
Even though these diseases are primarily caused by a single gene,
several different mutations can result in the same disease but with
varying degrees of severity and phenotype.</span>
Answer: Developmental biologist
Explanation:
<u>Undifferentiated cells are cells that are able to develop into a specific cell variant</u>. They are the basic cells in biology that all other cells derive from. An example is stem cells which are cells that could still become any kind of cell that the body needs.
<u>Differentiated cells are cells that have changed from one type to another one more specialized</u>. For example, a neuron is a differentiated cell because they have a certain type of gene expression that makes them specialized to perform functions in the brain.
Developmental biology is the study of how organisms grow and develop. For that purpose, it studies the genetic control of cell growth, differentiation of stem cells, regeneration, asexual reproduction and morphogenesis. All these processes gives rise to tissues, organs and the anatomy of an adult organism. So, this kind of scientist study several cellular processes carried out by undifferentiated cells which will become specialized.
