In the context of inherited traits in frogs, the statement that best describes a trait likely to be inherited by offspring is:
"A parent frog is born with an extra finger. The offspring of this frog can inherit extra fingers."
This statement aligns with the concept of genetic inheritance, where physical traits, like the number of fingers, can be passed down from parents to offspring through their genetic material. In this case, the presence of an extra finger in the parent frog indicates a genetic variation that can potentially be passed on to its offspring. This trait is determined by the frog's genetic makeup and is not acquired during its lifetime, making it more likely to be inherited by future generations.
