In humans, the gene for normal color vision, c, is dominant to the gene for red-green colorblindness, c; this trait is sex-linked and found on the x chromosome. the gene for brown eyes, b, is dominant to the gene for blue eyes, b. calculate the probable genotype and phenotype of the children born to blue-eyed women who is heterozygous for a color vision and a heterozygous brown-eyed man was color blind. parental cross-> x genotype probabilities: phenotype probabilities:

The circles, or orbits, for electrons are called energy levels. each level can hold only a certain number of electrons. add electrons to each level until you can't add any more. how many electrons can each level hold?
