PATHOLOGY

Detailed explanation-1: -This is because: Males have only 1 X chromosome, from their mother. If that X chromosome has the gene for red-green color blindness (instead of a normal X chromosome), they will have red-green color blindness. Females have 2 X chromosomes, one from their mother and one from their father.

Detailed explanation-2: -Colour blindness is one of the world’s most common genetic (inherited) conditions, which means it is usually passed down from your parents. Red/green colour blindness is passed from mother to son on the 23rd chromosome, which is known as the sex chromosome because it also determines your sex.

Detailed explanation-3: -The quick answer is that yes, a female can get a copy of the gene that leads to colorblindness from her father. In fact, if her father is colorblind she will most certainly inherit a copy of the colorblindness gene.

Detailed explanation-4: -Color blindness is caused by genes located on the X chromosome. It is a recessive disorder. Males inherit one X chromosome from their mother. So, the sons will be color blind if their mother is color blind.

Detailed explanation-5: -A colourblind mother and normal father would have colour blind sons and carrier daughters. Daughters will be normal phenotypically but they will be carrier genotypically.
