From all I have read and studied (I am a 2nd semester senior nursing student at a major university) Spina Bifida is not so much a chromosomal defect as a neural defect caused by a lack of folic acid during the very early stages of pregnancy.
This is why women who wish to get pregnant are encouraged to begin taking folic acid BEFORE they actually get pregnant.

Is a chromosome effected by albinism?

In albinism what chromosome number is affected?
Chromosome 9.
What are the possible genotypes of the parents with albinism?
Individuals with albinism typically have a recessive genetic trait, meaning they must inherit two copies of the albinism gene (aa) to express the condition. Therefore, the possible genotypes of the parents could be either both carriers (Aa), one carrier and one affected (Aa and aa), or both affected (aa). If both parents are carriers, there is a 25% chance for each child to be affected by albinism.
Which chromosomes carry albinism?
Albinism is primarily associated with mutations in genes located on chromosome 11, specifically the TYR gene, which encodes the enzyme tyrosinase important for melanin production. Other forms of albinism can be linked to mutations on different chromosomes, such as chromosome 15 (OCA2 gene) and chromosome 19 (SLC45A2 gene). These genes collectively influence melanin synthesis and distribution in the body, leading to the condition.
What are the chances of two parents who carry the gene for albinism an autosomal recessive disorder having a child without albinism?
If both parents carry the gene for albinism, which is an autosomal recessive disorder, there is a 25% chance their child will be affected by albinism, a 50% chance the child will be a carrier like the parents, and a 25% chance the child will neither have albinism nor be a carrier. Therefore, there is a 75% chance that their child will not have albinism, either being a carrier or completely unaffected.
Which chromosomes are affected by asthma?
All Of THEM!
Which genes are affected by albinism?
Albinism affects genes responsible for producing melanin, the pigment that gives color to skin, hair, and eyes. Mutations in these genes can result in a lack of melanin production, leading to the characteristic features of albinism such as pale skin, light hair, and vision problems.
Which chromosomes are affected by Zellweger syndrome?
all of them
How is chromosome affected by parkinson's disease?
In recent discoveries, 18 specific chromosomes are affected because of Parkinson's Disease. These chromosomes are numbered in chronological order.
Are albinos born sterile?
No, albinism does not inherently cause sterility. Individuals with albinism can reproduce, as their condition primarily affects pigmentation due to genetic mutations rather than reproductive capabilities. However, some health issues associated with albinism, such as vision problems, may impact their reproductive choices or opportunities. Overall, fertility is not directly affected by albinism itself.
What chromosome is Albinism located on?
Chromosome 9.
Why is albinism a genetic disease?
Albinism is not a disease. People with albinism have little or no pigment in their eyes, skin, or hair. They have inherited altered genes that do not make the usual amounts of pigmment called melanin. Albinism affects people from all races. Most children with albinism are born to parents who have normal hair and eye color for their ethnic backrounds. There are different types of albinism, but all forms are associated with vision problems.
