Question

Which evidence best supports the claim that mutations are a source of inheritable genetic variation?
(1 point)
• Mutations affect the way DNA is created through transcription.
• Mutations affect protein synthesis which impacts the way traits are expressed.
• Mutations are not inheritable from gametes because they are given from each parent.
• Mutations can only happen during meiosis because genes are inherited.

Answer 1

Mutations affect protein synthesis which impacts the way traits are expressed.

Reason: A change in DNA sequence can alter mRNA and the resulting amino acid sequence of proteins, changing their function and thus phenotypic traits; when such mutations occur in gametes (germline), they are passed to offspring and produce inheritable genetic variation.
