Web18 de jan. de 2000 · In an absolute sense, if two genes are "linked", it means that if a trait for one gene is passed on, then a specific trait for the other gene will be passed on 100% of the time, i.e. the genes are physically linked together: inseparable. WebFor Autosomal dominant and X-linked dominant, there is no question of a carrier since the affected allele will be dominant. For X-linked recessive, the carrier will always be the mother/female.Since she has 2 X-chromosomes, one can compensate for the function of the other non-functional chromosome. grasmachine hurenWebGenes that are located on the same chromosome are called linked genes.
