I am just repeating @emhart answer but wanted to highlight the semantic.
There are several ways an individual can inherit from its parents.
- Through transmission of DNA. An acquired trait cannot affect DNA sequence directly and therefore cannot be inherited genetically by the offspring (this sentence is the answer to your question). Note however, that the environment in which an individual is found and the amount of stress an individual is experiencing may affect its mutation rate. But this has nothing to do with transmission of an acquired trait.
- Non-genetics (or "environmental in the broad sense")
- Environmental in a very narrow sense. For example, a dam that a beaver transmits to its offspring, a good habitat that the parents had to fight for. Note in the broad sense, any non-genetic inheritence should be considered as being part of the environment. Environmental change that an individual has caused (niche construction) of fighted for can potentially be inherited by the offspring
- Cultural. For example a language, a method to hunt seals or a method to clean potatoes. Cultural modifications acquired by an individual can potentially transmitted to the offspring
- Epigenetics. It includes any modification over the DNA and histones and any content of the egg. Something an individual has lived can affect the types of epigenetic modifications that a parent can transmit to its offspring.
Genetic and epigenetic characteristics can be exclusively transmitted from parent to offspring (setting aside horizontal gene transfer and transduction), while environmental characteristics and cultural characteristics can potentially inherited between any two individuals. In the field of population genetics, the ratio of the phenotypic variance that is due to (additive) genetic variance over the total phenotypic variance in a population is called heritability (in the narrow sense).
There are plenty of important keywords in my (and @emhart's) answer. You might want to have a look at the wikipedia entries for all these concepts. You might also want to have a look at this answer.
