What type of chromosomal mutation occurred?
(a)
What type of chromosomal mutation occurred?
(a)
Read and analyze the given situation. Identify the disorder being described. **Do not use the term trisomy**
"People with this genetic mutation look alike because the affected chromosome is specific for the physical appearance. This happens when an additional chromosome 21 is found in their genetic material."
(a)
Read and analyze the given situation. Identify the disorder being described. **Do not use the term trisomy**
"This genetic mutation is rare - 1 in 6000 live births. This happens when a person has an extra chromosome 18."
(a)
Read and analyze the given situation. Identify the disorder being described. **Do not use the term trisomy**
"A person affected by this mutation usually exhibits clenched hands, cleft lip or palate, scalp defects, and others. This is due to an extra 13th chromosome."
(a)
Read and analyze the given situation. Identify the disorder being described. **Do not use the term trisomy**
"A person affected by this mutation usually exhibits short and webbed neck, low-set ears, and short stature. This happens when a female is missing an X chromosome."
(a)
Read and analyze the given situation. Identify the disorder being described. **Do not use the term trisomy**
"A person affected by this mutation usually exhibits mental retardation, facial defects, small head, and low birth weight. Babies with this condition have high-pitched cries. This happens when there is a partial loss of the fifth chromosome."
(a)
