Denning [Date] [Course title]
, Somatic mutations - Correct Ans: occur in any cell except germ cells and are not heritable
Germ-line mutations - Correct Ans: occur in gametes and are inherited
Autosomal mutations - Correct Ans: occur within genes located on the autosomes
X-linked and Y-linked mutations - Correct Ans: occur within genes located on X and Y chromosome,
respectively
Spontaneous mutations - Correct Ans: happen naturally and randomly and are usually linked to normal
biological or chemical processes in the organism
Induced mutations - Correct Ans: result from the influence of an extraneous factor, either natural or
artificial
Luria- Delbrück Fluctuation Test - Correct Ans: genetic mutations arise inthe absence of selection, rather
than being a response to selection
neutral mutation - Correct Ans: do not affect gene products or gene expression
β- Thalassemia - Correct Ans: Autosomal recessive blood disorder resulting from a reduction or absence
of hemoglobin
Sickle Cell Anemia - Correct Ans: autosomal recessive genetic disorder that causes abnormal
hemoglobin, resulting in some red blood cells assuming an abnormal sickle shape
Spinal Muscular Atrophy - Correct Ans: autosomal recessive genetic disorder caused by a genetic defect
in the SMN1gene, which encodes SMN, a protein widely expressed in all eukaryotic cells and
necessary for survival of motor neurons
