Question

Given below are two statements:
Statement (I): Heterosis refers to the phenomenon where the hybrid offspring exhibit superior trait performance compared to their parents.
Statement (II): Heterosis is primarily attributed to the combination of favorable alleles from each parent, resulting in enhanced trait performance of the hybrid offspring.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are true.
• B. Both Statement (I) and Statement (II) are false.
• C. Statement (I) is true but Statement (II) is false.
• D. Statement (I) is false but Statement (II) is true.

Hint:

Remember that hybrid vigor is the phenotypic manifestation of genomic complementarity.
Bringing divergent parents together combines favorable alleles, masking deleterious recessive mutations.

Answer 1

The Correct Option is A
