haemophilia and colour blindness are
Answers
Answer:
It is well established that colour-blindness and haemophilia are due to sex-linked genes. These genes appear to manifest themselves in all males who carry them. In women the gene for haemophilia is probably always recessive, the cases of alleged haemophilia in heterozygous women being very doubtful.

Haemophilia and color blindness are generic diseases.
Because both are X linked recessive genes, which means that men who inherit them will be color blind or have hemophilia.
Explanation:1. Hemophilia : - is a rare condition in which the blood does not clot properly. It mostly affects men . Hemophilia is normally an inherited disorder. A person is born with it.It happens because of a defect in one of the clotting factor genes on the X chromosome.
2.Colour blindness : Color-blindness is the inability to distinguish the differences between certain colors. This condition results from an absence of color-sensitive pigment in the cone cells of the retina, the nerve layer at the back of the eye. A person with color-blindness has trouble seeing red, green, blue, or mixtures of these colors. The most common type is red-green color-blindness, where red and green are seen as the same color.
