biology nord ic qtr b continuous learning center - credit bearing (tutor) chromosomal changes which change to the chromosome causes robertsonian translocation? arms of the chromosome are unproportioned, with extra or missing genetic material duplication of genes on the same chromosome part of the chromosome breaks off, causing missing genes on the chromosome movement of genes on the same chromosome

Explanation:

Robertsonian translocation is a type of chromosomal rearrangement where two acrocentric chromosomes (chromosomes with arms of unequal length) fuse at their centromeres. This results in chromosomes with arms that are unproportioned, having extra or missing genetic material. Duplication of genes on the same chromosome refers to a different type of mutation (duplication). Part of the chromosome breaking off (deletion) is another type of mutation. Movement of genes on the same chromosome (inversion or some types of intra - chromosomal rearrangements) is also a different phenomenon.

Answer:

arms of the chromosome are unproportioned, with extra or missing genetic material
