What does chromosome 12 determine?
Chromosome 12 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 12 spans about 133 million base pairs (the building material of DNA) and represents between 4 and 4.5 percent of the total DNA in cells.
How does DNA determine traits?
Traits are determined by genes, and also they are determined by the interaction with the environment with genes. And remember that genes are the messages in our DNA that define individual characteristics. So the trait is the manifestation of the product of a gene that is coded for by the DNA.
What does chromosome 9 determine?
Humans normally have two copies of this chromosome, as they normally do with all chromosomes. Chromosome 9 spans about 138 million base pairs of nucleic acids (the building blocks of DNA) and represents between 4.0 and 4.5% of the total DNA in cells.
What determines the traits of all organisms?
The traits an organism displays are ultimately determined by the genes it inherited from its parents, in other words by its genotype. Animals have two copies of all their chromosomes, one from each parent.
What do chromosomes do?
Chromosomes are the things that make organisms what they are. They carry all of the information used to help a cell grow, thrive, and reproduce. Chromosomes are made up of DNA. Segments of DNA in specific patterns are called genes.
What happens when you are missing chromosome 12?
Features that often occur in people with chromosome 12q deletion include developmental delay , intellectual disability , behavioral problems, and distinctive facial features. Most cases are not inherited , but people can pass the deletion on to their children.
What chromosome determines height?
In men, the Y chromosome is important for height (9). Short stature has been demonstrated in persons with deletions in the sex chromosome pseudoautosomal region that includes a homeobox-containing gene designated SHOX (1).
What is Trisomy 12 called?
Although trisomy 12 (+12) chronic lymphocytic leukemia (CLL) comprises about 20% of cases, relatively little is known about its pathophysiology.
