If the mother is a carrier of colour blindness and the father is normal, the possible genotype and
the phenotype of the offspring of the next generation, with the help of a punnet square
उत्तर
Colour blindness is an X-linked recessive disorder
- Mother is the carrier for colourblindness and Hence, the genotype of Mother must be XC X
- Father is normal, hence the genotype of the father must be XY
By using punnet square, the possible genotypes and phenotypes in next generation will be
| X | Y | |
| XC | XCX | XCY |
| X | XX | XY |
Possible Genotypes - XCX, XCY, XX and XY
Possible Phenotypes -
XCX = Carrier daughter
XCY = Affected son
XX = Normal daughter
XY = Normal son
