What are sections of a chromosome that are code for trait?
A section of chromosomes that codes for a trait can be called
Section of a chromosome that determines a single trait?
CODON
In what chromosome is the ear lobe trait located?
The ear lobe trait is not located on a specific chromosome, as it is a common genetic trait that is not influenced by a single gene or located on a specific chromosome. The presence or absence of ear lobes is determined by multiple genetic factors.
True or False A mutation is the part of a chromosome that carries information about a trait?
False. A mutation refers to a change in the DNA sequence of a gene or chromosome, not the specific part of a chromosome that carries information about a trait.
What does a match on the X chromosome signify in genetic testing?
A match on the X chromosome in genetic testing indicates a shared genetic trait or similarity between individuals, which can be used to trace ancestry or identify potential genetic disorders.
Is colorblindness genetic?
Yes. It is a sex-linked recessive trait found on the X chromosome.
What is x linked trait?
Normally sex-linked traits are carried only on the X chromosome, meaning a sex-linked gene can only be inherited from the father's X or the two mother's X's. However, there are occasions where the trait is carried down by the Y chromosome, meaning only the males would inherit it, and it would be expressed. This is very uncommon because the Y chromosome carries very little genetic material/information in comparison to the Y chromosome.
What is a section of DNA that determines a trait?
a section of DNA has information about a specific trait of an organism is called what?
What are genetics markers?
Genetic markers are areas on the chromosome which are in linkage disequilibrium with a known trait, ie they are inherited along with the trait. The markers do not have to cause the condition or trait to be observed, but they will always be inherited alongside the trait and therefore cna be described as a marker for that particular trait.
What makes something a sex-linked trait instead of just a regular trait?
A sex linked trait can only be found on the x chromosome such as hemophilia, color blindness, and muscular dystrophy. These are traits that can only be inherited through chromosomes instead of regular traits coming through genes.
What is a section of DNA that code for a trait?
A section of chromosomes that codes for a trait can be called
Is polydactyly common in men or women?
Polydactyly is more common in men, because it is a genetic disorder. Because females have 2 X chromosomes, a recessive trait passed down on one will be covered by the dominant trait on their other X chromosome for no polydactyly. Males though, have an X and Y chromosome which means that that the Y chromosome, carrying no trait for polydactyly, will not affect an X chromosome with the allele for polydactyly. Hence, polydactyly is found in men more than women.
