At an autosomal gene locus in humans, the allele for brown eyes is dominant over the allele for blue eyes. at another gene locus, located on the x chromosome, a recessive allele produces colorblindness while the dominant allele produces normal color vision. a heterozygous brown-eyed woman who is a carrier of colorblindness marries a blue-eyed man who is not colorblind. the woman becomes pregnant and an ultrasound test shows that the child is a boy. what is the probability that he will be colorblind? (enter the probability as a percent. enter the number only without the percent sign. for example, enter 100% as 100 and enter 12.5% as 12.5)
