How does genetic diversity lead to environmental disruptions?
It is now well established that high diversity at different trophic levels can enhance productivity, resource use, nutrient cycling and stability of marine systems. Loss of diversity, in turn, leads to increased rates of resource collapse, and to decreased water quality and recovery potential (Worm et al., 2006).
How does the environment cause genetic variation?
Internal and external environmental factors, like gender and temperature, influence gene expression. … Similarly, drugs, chemicals, temperature, and light are among the external environmental factors that can determine which genes are turned on and off, thereby influencing the way an organism develops and functions.
Increased genetic diversity leads to increased chance of species survival. Species with a limited variety of phenotypes and where all members of the species are similar to one another have a smaller chance of coping with environmental variability compared to a species with greater diversity.
What is influenced both by genes and by environmental factors?
Like most aspects of human behavior and cognition, intelligence is a complex trait that is influenced by both genetic and environmental factors. … Elements of intelligence include the ability to reason, plan, solve problems, think abstractly, and understand complex ideas.
How do environmental and genetic factors influence the growth of organisms?
How do environmental and genetic factors influence the growth of organisms? Genetic factors as well as local conditions affect the growth of organisms. − A variety of local environmental conditions affect the growth of organisms. Genetic factors affect the growth of organisms (plant and animal).
Does mutation increase genetic diversity?
Mutations can introduce new alleles into a population of organisms and increase the population’s genetic variation.
