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.
XX or XY OR XX(women can only be carriers) or XY(women with carrier gene that mates with male has 50% chance of spreading it to male) if male or female has either carrier gene or affected gene, then child has 50% chance of getting it.
Fragile X syndrom is not caused by a classical Mendelian mechanism. It is caused by repeated regions of DNA on the X chromosome. With the information given in the question and the possibility for a new mutation to have been generated in this generation all genotypes are possible. The gender of the affected child and state of health of the parents would help narrow down the possibilities.
they're genotype is most likely heterozygus or homozygus dominate.
i really dont know. the parents can be normal even if the child has rett syndrome. rett syndrome is caused by a mutation.
you could die we dis
Xx,Xx or Xx,xx or xx,xx

lets use "A" Aa and Aa aa
There is no way to be absolutely positive that your child will not have Morquio's syndrome if both parents have the gene, but there are genetic screenings to help prevent having a child with Morquio's syndrome.
Yes! The genotypes of the parents can only be "OO" (means two O genes) so both of them cannot give a "B" gene to the child
O- would be the only possible blood type for the child.
no if the one of the parents have it and it is genetic then yes. but in this case no because it is not genetic
Yes, it is quite possible. It does require both parents to have AO(+-) genotypes, which is somewhat rare, however.
Since Down Syndrome is not genetic and is a trisomy, dominant and recessive genes do not play a role and it is possible for two down syndrome parents to have a child without down syndrome.
Yes. It would take too long to explain genotypes and phenotypes, just know that it is possible.
No, it is possible for 2 parents with down syndrome to produce a child with no non-disjunction disorder because of a gamete is produced with an extra copy of the chromosomes.
Yes, it is possible. Parents who are O positive may have children who are O+ or O-, depending on the parents' genotypes.
No. Parents who have a child with Down syndrome do not have an increased chance in having another child with Down syndrome. Everyone has the same chance of having a child with Down syndrome, 1%.
Yes, it's possible but there are very slim chances. It depends heavily on the genotypes of both parents
Yes, it's possible but there are very slim chances. It depends heavily on the genotypes of both parents
If the parents had the genotypes AO and BO, then they could have a child with Type O blood (there would be a 25% chance of this occurring).

There is no way to be absolutely positive that your child will not have Morquio's syndrome if both parents have the gene, but there are genetic screenings to help prevent having a child with Morquio's syndrome.
Depends on the disease- dominant gene or recessive gene- and the genotypes of the parents.
