In a cross between a blue-eyed oohh woman and a blue-eyed oohh man, what eye color will the progeny have blue eye color.
- According to research on the genetics of eye color, blue eyes are caused by a mutation in the neighboring, unrelated gene HERC2.
- The gene OCA2, which controls the production of the brown pigment melanin, is silenced by this mutation. Today, between 20 and 40 percent of Europeans have blue eyes.
- The quantity of functional P protein that is generated is decreased by a number of frequent changes (polymorphisms) in the OCA2 gene.
- People with a variation in this gene have blue eyes instead of brown because less P protein implies less melanin is present in the iris.
- A disturbance in the normal generation of melanin brought on by OCA2 gene mutations results in visual issues and a loss of hair, skin, and eye color. Oculocutaneous albinism type 2 refers to oculocutaneous albinism brought on by mutations in the OCA2 gene.

Answer:
One factor limits a population at a time. Suppose the area that had only enough food for 500 armadillos suddenly had enough food for 2,000 armadillos, but only enough water for 1,000 armadillos. The population still couldn't grow to 2,000 armadillos. Water would keep the population at 1,000 armadillos. In this case, water is the limiting factor.
Explanation:
The size of a population is limited by the carrying capacity of the environment. The carrying capacity is the maximum number of individuals that an environment can support. The carrying capacity of an environment can be limited by the availability of food, water, shelter, and other resources. Biodiversity is the variety of life in an area. The carrying capacity of an environment can also be limited by the number of different species that can coexist in an area.
Answer:
i think option B is correct answer because plants also gets nutrient from the animal so , there is more chance to get the information about the animals that were found in that area and time.
