Answer: Bob received the gene for colour blindness from his mother.
Bob's genotype is likely XbY.
Explanation: Colour blindness is a disorder in which a person is unable to distinguish certain colours such as green and blue. Colour blindness is an X-linked (sex-linked) disorder, which means that colour blindness are carried on the X chromosome. Males are usually the sufferers because they have only one X chromosome which once affected will result in colour blindness while females are usually the carriers because they normally have two X chromosome and hardly do they have the two chromosomes affected except if the person is from a mother who is a carrier and a father who is a sufferer.
Bob's parents are likely to have one female with normal vision XBXB, one female who is heterozygous for colour blindness (a carrier) XBXb, a male with normal vision XBY and another male who is colourblind XbY.
