Outline of Final Research Achievements

For organisms, heritability of shape and size is one of the factors that directly affects the rate of evolution. For example, if body size is easy to inherit and larger body is more advantageous, it is expected that the body of the organism will evolve quickly in the direction to become larger. In this research, I aimed to understand the genetic mechanism controlling heritability. As a result, it was confirmed that there are multiple genes on the genome thought to have such functions.
