G Normal color vision in the human is due to a dominant gene, C, and is x-linked. The recessive form of the gene, c, causes the individual to be red-green color blind. A color blind woman marries a man with normal color vision. What are the possible phenotypes of children with respect to vision?

If a color blind woman marries a man with normal vision, the following progeny may be expected in the F2 generation: among the daughters, they are carriers for the disease; among sons, all are color blind.

Explanation:

Normal color vision in the human is due to a dominant gene, C, and is x-linked. The recessive form of the gene, c, if  color blind woman marries a man with normal color vision the possible phenotypes of children are

all daughters are carriers

all sons are color blind

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
