Indirectly, yes it does. But it can only act on genotypes through their phenotypes.
A Punnett square is used to lay out the possible genotypes of offspring based on the genotypes of the parents being bred. From this, the probabilities of certain phenotypes and genotypes can be determined.
Many possible genotypes, producing ,any possible phenotypes.
These genotypes are determined by a human's 23rd pair of chromosomes. If the subject is female, she has two X's reading XX. If it is male, then his genotype will read XY. There is a 50-50 shot of each. This is because a woman donates one chromosome (she only has two X's so it is inevitable that she will donate an X), and a man donates one of his. If a man donates his 'X' then there will be two X's and the child will be female. If he donates his 'Y' then the child will be male. Male is XY, female is XX. There are, however, other genotypes (XXY, XXX, XO...) and not all people have a phenotype that goes with their genotype.
Genotypes are not created by phenotypes, they are the alleles/genes of the organism. Genotypes (in combination with environment) produce phenotypes. It would be expected that the genotypes Bb and BB would produce the phenotype B.

the genotypes of their parents
The genotypes in which one or more alleles is dominant.
xx = normal female x- x = carrier female x- x- = female which has the sex-linked trait xy = normal male x- y = male which has the sex-linked trait
People receive a total of 46 genotypes from their parents.

When enough phenotypes in a family are known the genotypes can be infered.
The parents have normal genotypes, because Klinefelter's syndrome is not inherited.
