Usually, you can have an amniocentesis done in utero to detect any abnormalities. After birth, they can look at physical features, and then do a genetic screening to find out of the child has the chromosomal abnormality found in people with Down syndrome.
For more, see what the Mayo Clinic has to say:
Diagnostic tests that can identify Down syndrome include: * Amniocentesis. A sample of the amniotic fluid surrounding the fetus is withdrawn through a needle inserted into the mother's uterus. This sample is then used to analyze the chromosomes of the fetus. Doctors usually perform this test after 15 weeks of gestation. The test carries a one in 200 risk of miscarriage. * Chorionic villus sampling (CVS). Cells taken from the mother's placenta can be used to analyze the fetal chromosomes. Typically performed between the ninth and 14th week of pregnancy, this test carries a one in 100 risk of miscarriage. * Percutaneous umbilical blood sampling (PUBS). Blood is taken from a vein in the umbilical cord and examined for chromosomal defects. Doctors generally perform this test after 18 weeks of gestation. This test carries a greater risk of miscarriage than does amniocentesis or chorionic villus sampling. Generally, this test is only done when speed of diagnosis is essential.
What else can I help you with?
Can you tell a persons genes just by looking at them?
No, you cannot determine a person's genes just by looking at them. Genetic analysis through methods such as DNA testing is required to accurately identify a person's genetic makeup. Physical appearance alone cannot reveal someone's specific genetic traits.
What are genetic footprints?
Genetic footprints refer to the unique patterns found in an individual's DNA that can be used to identify them or trace their ancestry. These footprints are specific genetic markers or variations that are passed down through generations and can provide insights into a person's genetic history or relationships. Genetic footprints are commonly used in DNA analysis and forensics.
What information can be derived from a DNA chart wheel?
A DNA chart wheel can provide information about a person's genetic ancestry, health traits, and potential risk for certain diseases based on their DNA analysis.
How can a person's genotype for a trait be determined from his or her phenotype for the trait?
Genotype can be determined from phenotype through methods like genetic testing or pedigree analysis. By comparing the traits expressed by an individual with known genetic information, scientists can infer the genotype responsible for those traits. This process helps to understand the genetic basis of specific traits in individuals.
How many things can you find out about a person with one strand of hair?
With one strand of hair, it is possible to conduct a DNA test to determine some genetic traits and identify genetic disorders. Additionally, hair analysis can reveal drug use, toxic metal exposure, and certain health conditions. However, detailed personal information such as age, gender, or specific characteristics is not extractable from just one strand of hair.
Can you tell a persons genes just by looking at them?
No, you cannot determine a person's genes just by looking at them. Genetic analysis through methods such as DNA testing is required to accurately identify a person's genetic makeup. Physical appearance alone cannot reveal someone's specific genetic traits.
In humans the risk of passing on a genetic disorder to offspring can be assessed by?
You could make a pedigree which could identify carriers of a genetic disorder and individuals with the disorder. You could do blood tests to determine whether a person carries a gene for a particular genetic disorder. You could make a karyotype to determine whether there are any chromosomal abnormalities.
What is a pair of chromosomes carrying genes that determine whether a person is male or female?
Genetic chromosomes
How can someone determine if the carry the genetic code for cerebral palsy?
A person can determine if they carry the genetic code for cerebral palsy by having genetic testing done. Symptoms of cerebral palsy include lack of muscle coordination and variations in muscle tone.
Is chromosome analysis considered genetic testing?
Genetic testing is a type of medical test that identifies changes in genes, chromosomes, or proteins. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a person’s chance of developing or passing on a genetic disorder. More than 77,000 genetic tests are currently in use, and others are being developed. Genetic testing involves looking for changes in: Genes : Gene tests study DNA sequences to identify variations (mutations) in genes that can cause or increase the risk of a genetic disorder. Gene tests can be narrow or large in scope, analyzing an individual DNA building block (nucleotide), one or more genes, or all of a person’s DNA (which is known as their genome). Chromosomes : Chromosomal genetic tests analyze whole chromosomes or long lengths of DNA to see if there are large genetic changes, such as an extra copy of a chromosome, that cause a genetic condition. Proteins : Biochemical genetic tests study the amount or activity level of proteins or enzymes; abnormalities in either can indicate changes to the DNA that result in a genetic disorder.

Can you determine the genotype of a person just by looking at him or her?
No, the genotype of a person cannot be determined just by looking at them. Genotype refers to the genetic makeup of an individual, which is not visible. Physical appearance is determined by a combination of genetic and environmental factors.
What is genetics disorders?
A genetic disorder is something you inherit from birth , it could complicate the person's whole life. ex.(sickle cell anemia,SCIDS,Turner sydrome,ans many many others.)
What procedure allows investigations to determine the present or future genetic disorders of an individual?
Genetic testing is the procedure that allows investigations to determine the present or future genetic disorders of an individual. This involves analyzing a sample of blood or tissue for changes or mutations in a person's genes that may indicate a genetic disorder or their potential risk for developing one.
What is Stockholm sydrome?
Stockholm syndrome is the feelings of trust and affection that a kidnapped or otherwise taken person may feel towards their captor.
Can hair analysis determine if a person died of Legionnaires Disease?
yes because haie cells remain allived after human death.
Why can scientist use a person's DNA to determine if they are likely to develop a disease?
It carrys their genetic code and thus by examining it can find potential flaws.
What is gunpowder residue analysis?
Gunpowder residue analysis is a forensic technique used to detect the presence of gunshot residue on a person's skin or clothing. It can help determine if a person has recently fired a gun by identifying characteristic particles and chemical compounds associated with gunpowder.
