Werner syndrome has an autosomal recessive pattern of inheritance. Werner syndrome (WS) or Werner's syndrome, also known as "adult progeria ", [1] is a rare, autosomal recessive disorder [2] which is characterized by the appearance of premature aging. [3] Werner syndrome is named after the German scientist Otto Werner. [4]
Autosome. An autosome is any chromosome that is not a sex chromosome. [1] The members of an autosome pair in a diploid cell have the same morphology, unlike those in allosomal (sex chromosome) pairs, which may have different structures. The DNA in autosomes is collectively known as atDNA or auDNA.
e. A genealogical DNA test is a DNA -based genetic test used in genetic genealogy that looks at specific locations of a person's genome in order to find or verify ancestral genealogical relationships, or (with lower reliability) to estimate the ethnic mixture of an individual. Since different testing companies use different ethnic reference ...
Mendelian traits in humans. A 50/50 chance of inheritance. Sickle-cell disease is inherited in the autosomal recessive pattern. When both parents have sickle-cell trait (carrier), a child has a 25% chance of sickle-cell disease (red icon), 25% do not carry any sickle-cell alleles (blue icon), and 50% have the heterozygous (carrier) condition.

A genetic disorder is a health problem caused by one or more abnormalities in the genome. It can be caused by a mutation in a single gene (monogenic) or multiple genes (polygenic) or by a chromosome abnormality. Although polygenic disorders are the most common, the term is mostly used when discussing disorders with a single genetic cause ...
Frequency. 1 in 5,000–10,000 [4] Marfan syndrome (MFS) is a multi-systemic genetic disorder that affects the connective tissue. [6][7][1] Those with the condition tend to be tall and thin, with long arms, legs, fingers, and toes. [1] They also typically have exceptionally flexible joints and abnormally curved spines. [1]
The genotype of an organism is its complete set of genetic material. [1] Genotype can also be used to refer to the alleles or variants an individual carries in a particular gene or genetic location. [2] The number of alleles an individual can have in a specific gene depends on the number of copies of each chromosome found in that species, also ...
Autosomal dominant and autosomal recessive inheritance, the two most common Mendelian inheritance patterns. An autosome is any chromosome other than a sex chromosome.. In genetics, dominance is the phenomenon of one variant of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome.
