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.

What is Pathologic Anatomy ?</h3>
The field of medicine known as pathological anatomy and cytology analyzes tissues, cells, and their anomalies in order to aid in the diagnosis of diseases, particularly malignancies. Making the best therapy decisions requires an accurate assessment of the condition's kind.
