A/X X/A NIKKI SMITH **** Less than 1% of Fragile X Syndrome cases are a result of deletion, neither parent is a carrier. If a father is the carrier/full mutation, XY, he will pass the mutated gene to all of his daughters, all of his daughters will be carriers. If the mother is the carrier/full mutation, xX, with each pregnancy she has the possiblity of passing on fragile X as a pre-mutation (carriers) or full-Mutation to every child (male/female).
The parents have normal genotypes, because Klinefelter's syndrome is not inherited.
Well, if you're asking what are the possible genotype of parents affected, they could be either:MM or Mm because the syndrome is autosomal dominantIf either parent is affected, then the children are at least at a risk of 50% because of the dominance of the allele.
I DONT TOE
Mm
That depends entirely on the genotypes of the parents.

Possible alleles in the gametes of the parents
The parents have normal sex chromosome genotypes, XX and XY. The chromosomal error that causes Klinefelter's syndrome occurs during the formation of either of the parent's gametes during meiosis.
A Punnett square, which is a simple diagram used to predict the possible genotypes and phenotypes of offspring based on the genotypes of the parents.
The possible genotypes of the gametes in a genetic cross involving the keyword "genotypes" are determined by the specific alleles present in the parents. These genotypes can be represented by different combinations of alleles, such as homozygous dominant (AA), homozygous recessive (aa), or heterozygous (Aa).
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.
Yes, it is quite possible. It does require both parents to have AO(+-) genotypes, which is somewhat rare, however.
