Context: (i) The trait that expresses itself in F1 generation.(ii) The trait that keeps on passing from one generation to another.The appropriate terms for the statements (i) and (ii) respectively are:(a) Recessive trait, dominant trait (b) Dominant trait , recessive trait(c) Dominant trait , inherited trait (d) Recessive trait , inherited trait

The correct answer is (b) Dominant trait, recessive trait.

Step 1: Understanding the terms

• A dominant trait is one that is expressed or seen when a mixture of genes is present.
• A recessive trait is one that is only seen when a dominant gene is not present.

Step 2: Applying the terms to the context

• (i) The trait that expresses itself in F1 generation. This refers to the dominant trait because it is the one that shows up in the first generation (F1) when two different traits are bred.
• (ii) The trait that keeps on passing from one generation to another. This refers to the recessive trait because it can be carried in a person's genes without appearing in that person. It can then be passed to the next generation.

Therefore, the appropriate terms for the statements (i) and (ii) respectively are dominant trait and recessive trait.
