Answer 1

The true statement about deletion mutations is:

Deletion mutations can cause diseases such as cystic fibrosis.

While deletion mutations can have varying effects on organisms – including being detrimental, neutral, or beneficial – in the case of cystic fibrosis, a specific deletion in the CFTR gene is known to lead to the disease. Deletion mutations are not always detrimental, nor are they universally dominant or non-detrimental; their effects depend on the specific context and genes involved.
