Chapter08_ChromosomalMutations

Nora was studying genetics and came across a situation where a piece of chromosome broke off and attached to another chromosome. This type of mutation is called ___.

• trisomy

• translocation

• inversion

• deletion

Notice the abnormal 23rd chromosome.  This individual suffers from which chromosomal genetic disorder?

• Klienfelter's Syndrome
• Down Syndrome
• Cris-du-Chat Syndrome
• Andrew's Syndrome

A chromosome is found to be shorter than it's homologous match.  Which type of mutation would this most likely be?

• insertion
• deletion
• translocation
• inversion

The following karyotype illustrates an example of which syndrome?

• Turner's Syndrome
• Klienfelter's Syndrome
• Edward's Syndrome
• Down Syndrome

Cri-du-Chat Syndrome is caused by what kind of mutation?

• translocation
• inversion
• deletion
• addition

What process occurs during meiosis that can result in chromosomal disorders?

• crossing over
• non-disjunction
• anaphase I
• prophase II
