Nothing really leads to Down syndrome, it is just an extra chromosome in the 21st pair. (otherwise known as Trisomy 21)

How does the genetic code leads to variation?
hello
Mutations are a source of what in a species?
Genetic variation, which can lead to evoloution, and then potentially a new species.
What leads to genetic variation in a population?
Random mutations in an organism's DNA after reproduction.what lead to variations
What common genetic variation which causes a change in the amino acid sequence in the structure of hemoglobin leads to what disease?
Sickle cell
How does crossing over change the genetic material of chromatids?
During crossing-over, the genetic material from homologous chromosomes is swapped. This leads to a recombination of the genes. Simple example: Originally - ABCD alleles on one and abcd on the other. After crossing over - ABCd and abcD This creates offspring with non-parental phenotypes (traits), which are known as recombinants.
What is usually caused by a pair of homologous chromosomes failing to separate during meiosis?
nondysjunction, which leads to a genetic disorder known as trisomy 23, or down syndrome.
What are 2 examples of genetic diseases?
# They are SO numerous: Angelman's syndrome, Huntington's Disease, Hemophilia, Turner Syndrome, Tay-Schs disease, sickle cell anemia, Praeder-Willi Syndrome, neurofibromatosis, Klinefelter syndrome, phenylketonuria, Down's Syndrome, Cystic Fibrosis, celiac disease, color blindness, cri du chat, Canavan disease, Duchenne muscular distrophy, Charcot-Marie Tooth Disease, 22q11.2 deletion syndrome, achondroplasia and many, many more.
Does Down syndrome progress?
it leads to death
Which genetic disorder does an extra chromosome cause?
An extra chromosome can cause genetic disorders such as Down syndrome, which is caused by an extra copy of chromosome 21. This leads to developmental delays, intellectual disabilities, and certain physical characteristics.
Who is the oldest person with zellweger syndrome?
The oldest known individual with Zellweger syndrome lived into their late 30s. Zellweger syndrome is a rare genetic disorder that typically leads to severe physical and developmental disabilities, with most individuals succumbing to complications in infancy or early childhood.

How is down syndrome changing over time?
it leads to death
What leads to korsakoff syndrome?
"Korsakov's Syndrome" is a brain disorder caused by the lack of thiamine (vitamin B1) in the brain.
Why genetic variation leads to population stability?

What usual meiotic event leads to down syndrome In which parent?
Nondisjunction.
What is polydactyly a symptom of?
Polydactyly is a genetic disorder which leads to one having six fingers or toes. This is also known as hexadactyly. It is caused by an autosomal dominant gene. ~ Poly = many dactly = fingers and toes. Polydactyly means more than the usual number of fingers and/or toes. Some cases can be genetic but most are not and there can be any number (not necessarily 6).
What condition is present in a human embryo when it has 3x21 chromosomes?
A human embryo with 3 copies of chromosome 21 has trisomy 21, which leads to Down syndrome. This genetic condition is characterized by intellectual disability, distinct facial features, and an increased risk of other health issues such as heart defects and Alzheimer's disease.
