Solution

Color blindness:

  1. Yes. Color blindness is a Mendelian disorder.
  2. It is the inability to distinguish between colors, especially between primary colors like red, blue, and green.
  3. Color blindness is caused by a genetic flaw passed down from a parent's defective genes to their children.
  4. It occurs when some of the color-sensitive cells in the eyes, known as cones, are missing or malfunctioning.

Mendelian disorder:

  1. Mendelian disorders can be defined as a type of genetic disorder that arises due to alterations in one gene or as a result of abnormalities in the genome.
  2. Mendel's investigations into the modes of inheritance in pea plants laid the groundwork for the present knowledge of single-gene disorders in humans.
  3. These illnesses, which are also known as Mendelian or monogenic disorders, are brought on by gene mutations and may run in families.
  4. Such a condition can be found in an affected person from birth and be found based on family ancestry.
  5. Sickle Cell Anemia and Phenylketonuria are other examples of mendelian disorders.
