Explanation:
Seeing as the gene is dominate, the hair would still be white evening it's Ww. For the hair to be a different color both parent would need a recessive gene (w), though neither does, meaning all the kids would have white hair.
Since the Pitx1 gene codes for a protein crucial im lower limns development, a mutation occurring near Pitx1 gene will affect refikjs around the lower limbs but not those far away from it.
<h3>What are mutations?</h3>
Mutations refers to alterations or error that occur which change the original sequence of nucleotides in a DNA molecule.
The Pitx1 gene is a gene that codes for a protein that involved in development of the lower limbs.
A mutation near but outside of the coding region of Pitx1 may cause a loss of pelvic fins without pleiotropic effects on the pituitary gland and jaw because the pelvic fins form part of the lower limbs whole the jaws and the pituitary gland are not found in the lower limbs.
Therefore, the mutation occurring near Pitx1 gene will affect regions around the lower limbs but not those far away from it.

Answer:Over time, carbon-14 decays in predictable ways. And with the help of radiocarbon dating, researchers can use that decay as a kind of clock that allows them to peer into the past and determine absolute dates for everything from wood to food, pollen, poop, and even dead animals and humans.
Explanation:
Answer:
Dopamine.
Explanation:
Cocaine is used as a recreational drug and addictive in nature. It can be smelled or directly inhaled in the veins. This drug causes the feeling of restless and happiness.
The dopamine is the important neurotransmitters that regulates the mood and other biological activity of the body. The cocaine inhibit the reuptake of dopamine and leads to its accumulation in the brain. This might also break the blood brain barrier.
Thus, the answer is dopamine.
