Question

question 4 of 10
what is a karyotype?
a. a way to test for chromosomal mutations
b. the result of mutations in a genotype
c. the total number of mutations in a gene
d. a substance that causes mutations

Explanation:

A karyotype is a visual representation of an individual's chromosomes. It is used to detect chromosomal mutations such as aneuploidy (abnormal number of chromosomes) or structural changes in chromosomes. Options B, C, and D do not accurately describe what a karyotype is. Option B refers to the consequence of mutations rather than the karyotype itself. Option C is about gene mutations, not chromosomal ones. Option D describes a mutagen, not a karyotype. So, the correct answer is A as it correctly identifies the purpose of a karyotype which is to test for chromosomal mutations.

Answer:

A. A way to test for chromosomal mutations
