NGSS.HS-LS3-2

Mutated DNA sequences that can be passed from parent to offspring --

• occur in somatic cells (body cells)
• occur in gametic cells (sex cells)
• are rejected by meiosis
• only occur if the parent is exposed to harmful substances

Cri-du-Chat is a serious genetic disorder that results in the chromosomal mutation pictured. Analyzing the picture, Cri-duChat is caused by -

• addition of nucleotides in the p arm of the chromosome
• exchange if genes from the crossing over of chromosome 5 p arms
• loss of several genes on the p arm of chromosome 5
• loss of genes on the q arm of chromosome 5
