Answer: The correct answer is XcXc.

Colorblindness is a X linked recessive trait that is marked by the deficiency of color vision in an individual.

Since females carry two X chromosomes, therefore color blindness will be caused only when both the X chromosomes carry gene for it as if one X chromosome carries, the female will be carrier for it.

Thus, second option is the right answer that depicts the genotype of the color blind Grandma Minion.

Colour blindness is a sex-linked recessive condition in which the gene of colourblindness is situated on the X chromosome. The female is generally carriers and the male are diseased as they have one X chromosome in their genetic material.

The genotype of Grandma Minion for the disease will be:

Option B. [tex]\text{X}^{\text{c}} \text{X}^{\text{c}}[/tex]

This can be explained as:

  • The first gene [tex]\text{X}^{\text{c}} \text{X}[/tex] does not depict colourblindness as only one chromosome of the female have a gene for the disease which will make it deliverer but not diseased.

  • The third gene XX designates a normal woman as the gene for colourblindness is missing on both chromosomes.

  • The fourth option [tex]\text{X}^{\text{c}} \text{Y}[/tex]denotes a male having colourblindness as it contains a gene for disease on its X chromosome.

Therefore, for a female to be colourblind both of her XX chromosomes must have genes for the disease.
