Turner syndrome is caused by a missing or incomplete X chromosome in females. It is typically not inherited, but rather occurs as a random event during the formation of reproductive cells in one of the parents. It is not passed down from parent to child.
Having a sibling with Down syndrome does not directly increase the chances of giving birth to a child with Down syndrome. The risk is influenced by maternal age, not family history. If both parents are carriers of the genetic translocation for Down syndrome, the risk may be higher.
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.
Inheritance syndrome is typically inherited in an autosomal dominant pattern, meaning that a mutation in one copy of the affected gene is enough to cause the syndrome. This means that an affected individual has a 50% chance of passing the syndrome on to their offspring. Rarely, inheritance syndrome can also be inherited in an autosomal recessive or X-linked pattern.
Red-green color blindness is usually inherited through a recessive gene located on the X chromosome. This means that the condition is more common in males, as they only have one X chromosome. Females can be carriers of the gene without showing symptoms.
N/A no one can answer it because they never did have a job.
It could be inherited by the parents, that would be very likely, If the parents don't have color blindness, its not very likely.
His mother was Adeline Campbell and his father was Thomas Turner.
The parents have normal genotypes, because Klinefelter's syndrome is not inherited.
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%.
No. Parents of Down Syndrome typically are normal genetically and there is no test for parents to determine the possibility of a Down Syndrome offspring. There are no known external factors that are known to contribute to Down Syndrome. It is possible to test for Down Syndrome in the fetus.
No, CFC syndrome is caused by a sporadic mutation.
Turner syndrome is caused by a missing or incomplete X chromosome in females. It is typically not inherited, but rather occurs as a random event during the formation of reproductive cells in one of the parents. It is not passed down from parent to child.
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.
Marfan syndrome is found in 1 in every 5,000 - 10,000 births. If one of your parents has Marfan syndrome, you have a 50% chance of having Marfan syndrome.
Prader-willi syndrome occurs due to genetic mutation, it is believed that parents with a genetic abnormality, uneffected by the syndrome, pass the mutation to their children. Some studies suggest that the syndrome is due to missing genes in the paternal chromosome, but it may be a combination of both parents.
If night blindness is a recessive trait, the couple's fourth child will exhibit the phenotype associated with night blindness only if both parents carry the recessive allele (i.e., they are either carriers or affected). If at least one parent has the dominant allele for normal vision, the child will not express night blindness. Therefore, the phenotype of the fourth child could be either normal vision or night blindness, depending on the genetic makeup of the parents.
