Surprising new evidence has shown that, in some cases, environment factors can modify chromosomes in such a way that changes the expression of genes without changing themselves or any part of the DNA sequence. These modifications are called epigenetic effects. Epigenetic effects can sometimes even be passed from generation to generation. In what way would this kind of "inheritance" be an exception to Mendel's laws?
A. According to Mendel's laws, the effects of our environment are not passed on to the next generation.
B. Since they are scientific laws, Mendel's laws can't be violated even if there is new evidence to the contrary.
C. These effects must be caused by mutations.
D. Mendel's laws apply only to pea plants, not all sexually reproducing organisms.
A. According to Mendel's laws, the effects of our environment are not passed on to the next generation.
