I n the F1 generation, there will be no recessive offspring but in the F2 generation there is a 25% of offspring being recessive.
You can find more info about percentages by observing images. called Punnett Squares.

Answer:
Man's genotype: XᴮY
Woman's genotype: XᴮXᵇ
Daughter's genotype: XᵇXᵇ
The daughter is not the man's child.
Explanation:
Color blindness is a sex-linked trait caused by a recessive allele located in the X chromosome (Xᴮ=normal vision; Xᵇ-color blind).
Women have two X chromosomes, while men have an X and a Y chromosomes. For that reason, women need to have two recessive alleles to be color blind, while men only need one Xᵇ to be colorblind.
Since the man has normal color vision, his genotype would be XᴮY.
If the daughter is her father's, she would have inherited his dominant Xᴮ allele, so she would have normal vision. However, she is colorblind, so her genotype is XᵇXᵇ. She is not the man's daughter.
The mother also has normal color vision, but her daughter inherited a recessive allele from her, so her genotype is heterozygous XᴮXᵇ.
Cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells.
