it is found in the coding region of the pitx1 gene.

it results in a protein that is no longer functional.

it occurred in a similar dna region in freshwater stickleback populations all over the world.

Researchers discovered that the genetic mutation causing the loss of pelvic spines is found in the coding region of the Pitx1 gene.

Changes in Pitx1 gene happen in response to the changes of the environment where the fishes live. The fishes undergoes changes without compromising its abilities

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
