Model Answer
(c) Dominant trait, Inherited trait
Statement (i) describes the trait expressed in F1 generation — this is the dominant trait. Statement (ii) describes a trait passed from generation to generation — this is an inherited trait.
Explanation
- "Dominant trait" is the one expressed when two different copies of a gene are present (as seen in F1).
- "Recessive trait" is hidden in F1, so option (a) and (b) are wrong.
- The trait in statement (ii) keeps passing across generations, which fits "inherited trait," not specifically "recessive." This rules out option (b).
- Hence (c) is correct.
