Which conclusion fits data where a trait appears in parents and in most offspring?
Which conclusion fits data where a trait appears in parents and in most offspring?
Tap to reveal answer
The trait is likely inherited. Traits passing from parents to offspring indicate genetic inheritance.

Identify the correct comparison: if Trait A count is 12 and Trait B count is 5, which is more common?
Identify the correct comparison: if Trait A count is 12 and Trait B count is 5, which is more common?
Tap to reveal answer
Trait A is more common. Compare counts: 12 is greater than 5, so Trait A occurs more often.

What is a learned behavior (not an inherited trait)?
What is a learned behavior (not an inherited trait)?
Tap to reveal answer
A behavior gained from experience or teaching. Unlike inherited traits, these develop through practice and observation.
