Which of the following best explains why a Robertsonian carrier may have no health problems due to his or her chromosome rearran
gement? A.Genes on the lost p arms can be found elsewhere in the genome.
B.There are no genes found on any of the p arms of acrocentric chromosomes.
C.All acrocentric p arms contain the same base sequence.
D.The long q arm chromosome copies the genetic information from the p arms before they are lost.
Robertsonian translocation occurs of 2 acrocentric chromosomes with no problems for the person carrying it in balanced form. In an unbalanced form, it produces chromosome imbalance leads to mental disorder or malformations.
In this translocation p arm or long arm join with other chromosome's long arm, carrier is normal due to the presence of 2 copies of all chromosome arms so there will be all the copies of essential genes.
