Question

why are advantageous traits more likely to be passed onto offspring? because they come from recessive alleles. because they come from dominant alleles. because they are more likely to survive and reproduce. because the trait is an acquired phenotype.

Explanation:

To determine the correct answer, we analyze each option:

• Option 1: Recessive alleles don't inherently make a trait more likely to be passed on just because they are recessive. Advantageous traits can be from dominant or recessive alleles, so this is incorrect.
• Option 2: Dominant alleles aren't the sole reason; a dominant allele trait isn't necessarily advantageous. Advantage depends on survival/reproduction, not dominance, so this is incorrect.
• Option 3: Advantageous traits help organisms survive and reproduce (natural selection). Organisms with these traits are more likely to pass them to offspring, which matches the concept.
• Option 4: Acquired phenotypes (like muscle from exercise) aren't passed to offspring (Lamarckian idea, disproven). Traits passed are genetic, so this is incorrect.

Answer:

C. Because they are more likely to survive and reproduce.
