Answer:
A. chromosome
Explanation:
Chromosomes are typically what you see in a chart like karyotype that shows all the chromosomes of a particular organism. These are the highly condensed structures of DNA during replication which makes it easy to transfer DNA during replication.
A sex-linked trait is a trait that is carried by the X chromosomes in females but it is not expressed(the phenotype). Females are only carriers because they have two copies of the X chromosome [one of them carries the trait and the other does not]. Males who inherit one copy of the X chromosome often get the trait (because the trait is in either one copy or the other of the X chromosome) and express it while their Y chromosome would became recessive. Thus, only males express sex-linked traits such as hemophilia or color blindness
In drastic reduction, what is being described above is the process called the founder effect. The founder effect is also the other term called in which it applies the definition above. This is made when a population has been created with the means of having small numbers and not too many individuals.
