Question

If a genetic mutation occurs on one of the first 22 pairs of chromosomes and only one copy of the gene is needed for expression, what type of genetic defect is present?.

Answer 1

The presence of a genetic mutation on one of the first 22 pairs of chromosomes, where only one copy of the gene is needed for expression, indicates an autosomal dominant genetic disorder.

Step-by-step explanation:

If a genetic mutation occurs on one of the first 22 pairs of chromosomes and only one copy of the gene is needed for expression, the type of genetic defect present is known as an autosomal dominant genetic disorder.

In an autosomal dominant disorder, a mutation in one copy of the gene is enough to cause the disorder. This means that if an individual inherits the mutated gene from only one parent, they will show the symptoms of the disorder. Some examples of autosomal dominant genetic disorders include Huntington's disease, Marfan syndrome, and achondroplasia.

Answer 2

An autosomal condition is the type of genetic defect that would be present.
