10.3 Gene pools and speciation: Inheritance of Acquired Characteristics

Environment can trigger heritable changes in epigenetic factors

Understanding that:

- A gene pool consists of all the genes and their different alleles, present in an interbreeding population.
- Evolution requires that allele frequencies change with time in populations
- Reproductive isolation of populations can be temporal, behavioural or geographic
-Speciation due to divergence of isolated populations can be gradual
-Speciation can occur abruptly
