Darwinism explains all of the following except
- A offspring with better traits that overcome competition are best suited for the environment
- B variations are inherited from parents to offspring through genes
- C within each species, there are variations
- D organisms tend to produce more number of offspring than can survive
Answer & Solution
Correct Answer
(B) variations are inherited from parents to offspring through genes
Step-by-step Solution
Detailed explanation
(B) variations are inherited from parents to offspring through genes,
Option (b) is incorrect as Darwinism does not address genetic inheritance; Mendel's later work explained how traits are passed through genes. Darwinism covers natural selection principles seen in (a), (c), and (d): organisms with advantageous traits (a) survive and reproduce more successfully, variations within species (c) allow adaptability, and overproduction of offspring (d) creates competition, ensuring only the fittest survive. These principles drive evolutionary change.
