Selective breeding for large size and sweetness in oranges

Steps:

• Identify desired traits: extra-large size and sweet taste.
• Review table data for each plant type's size and sweetness.
• Select types exhibiting both traits to maximize inheritance in offspring.
• Pair types 2 (large, sweet) and 4 (extra-large, sweet) for breeding.

Why C is correct:

• Selective breeding requires choosing parents with target traits, ensuring high probability of passing large size and sweetness genes to progeny.

Why the others are wrong:

• A: Types 1 and 2 lack consistent extra-large size in type 1.
• B: Types 1 and 3 include sour taste in both, opposing sweetness goal.
• D: Type 5 likely lacks one or both traits, diluting desired outcomes.

Final answer: C
