At an Autosomal Gene Locus in Humans,the Allele for Brown

Short Answer

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 has a child with a blue-eyed man who is not colorblind.An ultrasound test shows that the child is a girl.What is the probability that she 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)
