The male dwarf's father was of normal height; that is, homozygous recessive for achondroplasia. Consequently, the dwarf man of this exercise was heterozygous for the character (say Aa) because this condition is autosomal dominant.
He also has normal vision reason why he is X-NY and X-N which represents the X chromosome with the dominant N allele for normal vision. The woman is color blind and hence a homozygous recessive X-nX-n and of normal height.
