Question

One possible result of chromosomal breakage is for a fragment to join a nonhomologous chromosome. What is this type of chromosomal alteration called?

Answer 1

Answer:

Translocation

Explanation:

Changes in chromosome include deletions, duplications, inversions, and translocations.

• Deletion occurs when an end of a chromosome breaks off.
• Duplication is the presence of a chromosome segment more than once in the same chromosome.
• Translocation is when a fragment of chromosomal breakage join a nonhomologous chromosome.
• Reciprocal translocation is a chromosome abnormality caused by exchange of parts between non-homologous chromosomes.
• Robertsonian translocation occurs when two non-homologous chromosomes get attached, meaning that given two healthy pairs of chromosomes, one of each pair "sticks" together.
