This condition is genetically determined and is more common in males, affecting about 8%. In contrast, it impacts only about 0.5% of females due to its sex-linked nature. This genetic trait is carried on the X-Chromosome.

For females to exhibit color blindness, both X-Chromosomes must carry the deficiency. Males, having only one X-Chromosome, are more likely to display the trait if it is present.

If a color-blind female has children, all of them will inherit the deficient gene. This means a male born to a color-blind female will invariably be color-blind since he receives his X-Chromosome from his mother, and all of her X-Chromosomes carry the defective gene.

There are various types of color vision deficiencies. To delve deeper into this topic, you can explore the website Colblindor, which offers extensive explanations and tests to help identify your specific deficiency.
