Correct and rewrite the statements by changing the biological term that is underlined for each statement:
The theory of Inheritance of Acquired Characters was proposed by WATSON AND CRICK.
Topic: Lamarck — inheritance of acquired characters
Answer
The theory of Inheritance of Acquired Characters was proposed by LAMARCK.
Rewrite the WHOLE statement with the correction, as the question asks — writing only the corrected word may lose the mark.
LAMARCK proposed that characters ACQUIRED during an organism’s lifetime are passed to its offspring — a giraffe stretching its neck producing longer-necked young. The theory is rejected, because changes to body cells do not alter the genes in the gametes. WEISMANN disproved it by cutting the tails of mice for 22 generations, every one of which was born with a tail.
WATSON AND CRICK proposed the DOUBLE HELIX structure of DNA in 1953 — an entirely different contribution.
The three names of this chapter: LAMARCK (acquired characters, rejected), DARWIN (natural selection, accepted), WATSON AND CRICK (structure of DNA).
