Color blindness is a sex linked trait.Explain with the help of a cross
Please find below the solution to the asked query
Colour blindness is X-linked recessive disorder because of which a person is not able to distinguish between some of the colours, which other people can recognise easily. In this disease, females become affected only when they carry a gene for colour blindness on both X chromosomes and become carrier when they contain affected gene on only one X chromosome. The male gets affected when it carry affected gene on its X chromosome. Hence, the genotype of affected female will be XC XC , carrier female will be XCX and affected male will be XC Y. This can be depicted by the following cross:
Parents XC XC X XCY
Gametes XC XC Y
Offsprings XCXC XCY
Affected female Affected male
child child
Hope this information will clear your doubts about the colour blindness.
