Mendel collected evidence by doing careful experiments with pea plants. Which statements did his evidence directly support? A : Alleles carry the code for proteins in segments of RNA.
B : Hereditary factors (alleles) do not combine or mix. Instead, they are passed on in the same form they were inherited.
C : Different offspring of the same parents inherit identical characteristics.

B : Hereditary factors (alleles) do not combine or mix. Instead, they are passed on in the same form they were inherited

Explanation:

After Gregor Mendel performed experiments on over 20,000 pea plants in the 19th century, he was able to come up with the Laws of Heredity.

These laws showed that each parent passed on a single allele to their offspring but these alleles did not mix. Rather, they were passed on as they were and the dominant allele was the one that would manifest in the offspring.
