Question

expressed traits quick check
when scientists analyzed the variations of color expressed in monkey flowers, what did they realize about the offspring of purple monkey flowers? (1 point)
the traits expressed did not result from changes in the genetic code.
the traits expressed did not result from frameshift mutations.
the traits expressed did not result from environmental factors.
the traits expressed did not result from changes in pollination.

Explanation:

Studies on monkey flower color variation showed that the purple flower trait and its inheritance in offspring are not caused by changes to the genetic code itself, but rather by epigenetic modifications or regulatory changes that don't alter the DNA sequence. The other options are incorrect: frameshift mutations are a type of genetic code change (not relevant here), environmental factors can affect traits but this was not the key finding, and pollination changes do not explain the offspring trait consistency.

Answer:

A. The traits expressed did not result from changes in the genetic code.
