<u>Answer</u>: A heritable trait can be changed from one generation to another.

<u>Explanation</u>:

  • The concept of <em>descent with modification</em> was given by Darwin which simply states that the traits are passed on from the parents to the offsprings.
  • The traits that can be passed on are known as <em>heritable traits</em>.
  • These traits are passed on with the help of the genes.
  • So this passing on of traits explains the term <em>descent</em> in this concept. However, there are always chances that these heritable traits can be changed due to environmental factors or due to the process of recombination and thus the term <em>modification</em>.
  • So <em>descent with modification</em> means that a<em> heritable trait is passed from parents to offspring but it can be changed from one generation to another.</em>
