Common ancestry, hope this helps!
A mix of red and white alleles would be Rr which is a red flower
Answer:
The sequence data that would support this hypothesis would involve there being relatively more differences found between the three mitochondrial genes' sequences of the La Plata River dolphin and the sequences of the Chinese River dolphin.
There should also be fewer differences between the three mitochondrial genes' sequences of the La Plata River dolphin and the sequences of the Amazon River Dolphin.
Explanation:
This is because fewer differences between the mitochondrial gene sequences of two species indicate closer relatedness and more differences indicate lower relatedness.
In my opinion, it is harmful. As said in the text “The sickle cell mutation causes hemoglobin to become less soluble and stick together when blood oxygen levels are low. In turn, red blood cells with clumped hemoglobin become sickle-shaped, which can lead to pain, swelling of the hands and feet, frequent infections, and eye problems.” So basically, (in my own words) when blood oxygen levels are low, the sickle cell mutation makes hemoglobin less soluble, causing it to cling together. As a result, sickle-shaped red blood cells form, causing discomfort, swelling in the hands and feet, frequent infections, and vision issues.
