WebDec 9, 2024 · Gene: ↑ A section of DNA that contains the instructions for a trait. Genetic Diversity: ↑ The overall diversity in the DNA between the individuals of a species. Mutation: ↑ A change in an organism’s DNA. This can be a change of a single letter or a much bigger change of hundreds of letters at once. WebApr 10, 2024 · We could not detect any effect of fragmentation on the genetic diversity, probably because the high dispersal abilities of T. crassispinus counterbalance any detrimental genetic consequences of fragmentation. Nevertheless, fragmentation still impacts the species density as well as the social structure of its colonies. globus award 2022 https://ponuvid.com
