QUESTION:-

Which is an environmental factor that affects skin color in humans?

O number of genes inherited

O amount of sunlight absorbed

O number of linked genes

O amount of food consumed

ANSWER:-

AMOUNT OF SUNLIGHT ABSORBED.

Number of gene for color of the skin is same in all the human beings and also it's a genetic factors is there will be any absence of gene due to its deletion AMOUNT OF SUNLIGHT it is variable in variable reasons which is a imp factor for the color in variation in earth. In regions near to the equator have high amount of the light so they have darker skin color then the people near the poles as there is less amount of light .Number of gene inherited is also same for each and every individual for single species for human which is 378 gene loci and if there is any variation in number due to any genetics disorder it would be a genetic factor again.amount of food consumed is different for different people with same color in same region as it only depends on the work which is done by the individual in the society for its existence. though it is a environmental factor bit it didn't effect color of the species.

SO ACCORDING TO ABOVE DETAILS WE CAN CONCLUDE (2) AMOUNT OF THE SUNLIGHT IS THE ENVIRONMENTAL FACTOR WHICH IS RESPONSIBLE FOR THE COLOR OF THE SKIN IN HUMANS
