Down syndrome is a trisomy of the 21st chromosome as opposed to an allelic inheritance through the X chromosome. Trisomy is a somatic disorder caused
by improper division during gametogenesis (usually of the ovum) that results in 3 copies of the 21st chromosome in the egg once it is fertilized.

Is waardenburg syndrome caused by a dominant or recessive allele?
Waardenburg syndrome is typically inherited in an autosomal dominant pattern, meaning that only one copy of the mutated gene is needed to develop the condition. However, there are rare cases where it can be inherited in an autosomal recessive pattern, requiring two copies of the mutated gene.
The inheritance of Marfan syndrome is an example of?
The "autosomal dominant" method of inheritance. if your question as Marfan syndrome is the result of inheriting a single allele.

Is Edwards syndrome lethal or terminal?
Edwards syndrome, also known as trisomy 18, is a genetic disorder that is often severe and can be life-threatening. Many babies born with Edwards syndrome have significant health problems and developmental delays, which can result in a shortened lifespan. The majority of babies with Edwards syndrome do not survive beyond the first year of life.
The most common autosomal abnormality is seen is a person with?
The most common autosomal abnormality seen in a person is Trisomy 21, which causes Down syndrome. This occurs due to an extra copy of chromosome 21, leading to developmental delays and physical characteristics like slanted eyes and a flat facial profile.
Dose marfan syndrome have to be on a x chormose?
Marfan syndrome is caused by a mutation in the FBN1 gene, which is located on chromosome 15 and is inherited in an autosomal dominant pattern. It is not linked to the X chromosome. Both males and females can inherit and display symptoms of Marfan syndrome.
Is apert syndrome autosomal or sexlinked?
Apert syndrome is a autosomal dominant genetic disorder, meaning that only one copy of the mutated gene from either parent is necessary to inherit the condition. It is not sex-linked.
Is Edwards syndrome autosomal or sex linked?
Google has the answer for everything.
What are the history of disease?
It is named after John H. Edwards, who first described the syndrome in 1960. It is the second most common autosomal trisomy, after Down Syndrome, that carries to term.
Is sickle cell anemia a sexlinked trait?
Nope! The disease is equally in both males and females. This means that it is autosomal.
Is angelman syndrome autosomal?
"Autosomal" means the syndrome or disorder of interest is pertaining to a chromosome that is not a sex chromosome, either X or Y. Angelman and Prader-Willi Syndrome are both caused by a deletion (or disruption of a gene) on chromosome 15, which is an autosomal chromosome and not a sex chromosome. Therefore, yes, Angelman syndrome is considered an autosomal syndrome.
Is Zellweger syndrome dominant or recessive?
Zellweger syndrome is autosomal recessive.
Can Edwards' syndrome be prevented?
Edwards' syndrome cannot be prevented
