Spina bifida doesn't follow a strict inheritance pattern, but hereditary factors do play some role, though it is not completely understood yet.
Mothers who have had one child with spina bifida have a 3-4% chance of their next child having spina bifida, while the general population only has a 0.1-0.2% chance. In the case a pregnant woman has a family history of spina bifida, it is recommended that they take a higher dose of folic acid than other pregnant women. Here again, folic acid plays a role in preventing neural tube defects (like spina bifida), but the mechanism is not well understood.
Also, for an unknown reason, it is more prevalent in female children than in male children.

Is spina bifida a sex-linked gene?
The Spina Bifida birth defect is autosomal.

What is required for an individual to have a sex-linked disorder?
A sex-linked disorder is when a mutation of genes overrides the normal function of a another gene. For example, male-pattern baldness is a sex-linked disorder.
Is hemophilia a defect?
Hemophilia is a genetic mutation of the sex-linked X chromosome.
Is progeria autosomal or sex-linked?
Progeria is neither autosomal nor sex-linked. It is caused by a spontaneous mutation in the LMNA gene, which is located on chromosome 1.
Is the white eye mutation in Drosophila was shown to be sex-linked and caused by a gene residing on chromosome x?
Yes, the white eye mutation in Drosophila is indeed sex-linked, as it is located on the X chromosome. This mutation is caused by a defect in the gene that codes for eye color, resulting in white eyes instead of the typical red color found in wild-type flies.
Is digeorge syndrome dominant autosomal or sex-linked?
DiGeorge syndrome is not caused by a single gene mutation, but rather by a deletion of a portion of chromosome 22. It is not inherited in a simple Mendelian pattern like dominant autosomal or sex-linked traits.
How does a mutation in a sex differ from a from a mutation in a non-sex cell?
A mutation in a sex cell, such as a sperm or egg cell, can be passed on to offspring and affect future generations. In contrast, a mutation in a non-sex cell will only affect the individual and is not passed on to offspring.
What are similarities between sex linked gene and carrier?
Both sex-linked genes and carriers involve the inheritance of a specific gene. Sex-linked genes are located on sex chromosomes, while carriers typically refer to individuals who possess a recessive genetic mutation but do not exhibit the associated trait. In both cases, these genetic traits can be passed down to offspring.
How does a mutation in sex cell differ from mutation in a non sex cell?
A mutation in a sex cell may be passed on to an offspring. A mutation in a somatic (body) cell cannot be passed on to an offspring, but can potentially cause cancer in the person who has the mutation.
How does a mutation in a sex cell differ in a mutation in a non-sex cell?
A mutation in a sex cell may be passed on to an offspring. A mutation in a somatic (body) cell cannot be passed on to an offspring, but can potentially cause cancer in the person who has the mutation.
