Sagot :
The genes involved in albinism are not linked. Gene mapping enables the localization of different genes on specific chromosomes.
Gene mapping and karyotype
Gene mapping refers to the genetic techniques used to establish the locations of specific genes on the chromosomes.
Moreover, a karyotype is a preparation of the set of condensed chromosomes in the metaphase stage, which are ordered according to their length.
In this case, it is possible to conclude that the four genes involved in albinism are not linked because they are found on different chromosomes (chromosomes 11, 15, 9 and 5).
Since albinism is passed from parents to offspring in an autosomal recessive inheritance pattern, a person can receive this trait by receiving two copies (one of each parent) for the four mutated genes involved in albinism.
