GENETICS Two genes (A and B) for red-green colourblindness are located on the X chromosome. Both genes must be recessive or gene A must be recessive and gene B must have the dominant allele ß for the person to be red-green colourblind (see table below). If a father with genotype aß and a mother with a genotype AaBb reproduce, what is the probability that their child will be affected? More info:AlleleDominanceContributes tocolourblindness?
