What is the type of genetic inheritance of daltonism, Biology

Assignment Help:

What is the type of genetic inheritance of daltonism? Is daltonism more frequent in men or in women? What is the physiological explanation for the daltonism?

Daltonism is a recessive X-linked inheritance (gene situated in the nonhomologous portion of the X chromosome).

Daltonism is more frequent in men as in them only the single X chromosome needs to be affected for the disease to manifest. In women it is essential for both X chromosomes to be affected for the disease to come out.

The disease appears because of a defect in the gene that codifies a retinal pigment sensitive to red.
