No. It is due to a non-disjunction problem when the sperm and egg meet to form a zygote.
Down's syndrome is slightly more common among males with most studies showing about 106 to 125 boys for every 100 girls.
Yes

autossomal
Down syndrome
Autosomal means that it concerns an autosome--a chromosome other than a sex chromosome. Down syndrome is caused by an additional copy of the 21st chromosome. Since the 21st chromosome is not a sex chromosome, Down syndrome is autosomal.
Down syndrome is neither dominant nor recessive. Actually, it is considered to be an "autosomal" trait. This occurs when there is damage to the chromosome.
Nope! The disease is equally in both males and females. This means that it is 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.
Disorders, such as Down's Syndrome, are caused by nondisjunction.
Zellweger syndrome is autosomal recessive.
Yes, Marfan syndrome is autosomal dominant.
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.
Down syndrome is neither dominant nor recessive.It is "autosomal" or "other"; it is simply an error in the translation process of Chromosome 21 (three copies instead of two). Instead of 46 chromosomes, a person with Down syndrome will have 47.
it is rarely inherited, and is often spontaneous. but when inherited, it is considered autosomal dominant condition and is usually passed down from someone with the condition to all of their offspring
Yes.Autosomal deletion syndrome affecting chromosome 5..
