Fragile X Syndrome
Fragile X Syndrome
Chromosome maps display the relative positions of genes, genetic markers, and other DNA sequences along a chromosome. This information can help researchers understand the genetic basis of diseases, evolutionary relationships, and genetic variations within a population.
Deletion Syndrome or Williams Syndrome
Females have two X chromosomes, allowing them to be carriers of sex-linked genetic disorders on one X chromosome while having a normal allele on the other X chromosome. Males have only one X chromosome and one Y chromosome, so any genetic disorder on their single X chromosome will manifest as the disorder rather than being masked.
The probability would be 0.5 or 50%. A heterozygous woman will pass on the X chromosome with the recessive allele to 50% of her sons, and since the disorder is recessive, the son would only have the disorder if the X chromosome with the recessive allele is inherited from the mother.

Down syndrome is a chromosomal disorder. It is caused by having 1 extra chromosome (chromosome 21).
Additional chromosome
No, Down's syndrome is only a human genetic disorder. Those with the disorder have an extra chromosome. Raccoons do not get this particular genetic disorder.
Sounds like the disorder is genetic and located in his x-chromosome.

Deletion Syndrome or Williams Syndrome
PKU is described as an inherited, autosomal recessive disorder.
