Why can inbreeding be potentially harmful to populations?

Inbreeding can be harmful to populations because it increases the likelihood of genetic disorders and reduces genetic diversity, making the population more vulnerable to diseases and environmental changes.


Which change would decrease the population of small fish the most?

Overfishing of small fish would decrease their population the most since it directly reduces the number of individuals in the population.


How does genetic drift lead to a change in a populations gene pool?

Genetic drift reduces variation in a population through allele loss, there are 2 situations of GD: a) Bottleneck effect: number of individuals is reduced significantly by a random event b) Founder effect: few individuals are separated and establish their own population both situations result in different allele frequency representations in new populations from their previous population`s


Does reducing the use of vehicles help save the world?

In a way it does. It reduces carbon dioxide, which reduces poisonous fumes and greenhouse gases in the atmosphere, which reduces global warming, which reduces deaths among various populations. It goes a long way.


How can reproductive isolation lead to speciation?

Reproductive isolation separates the reproduction of one population into two populations. Over time after generations, the two separate populations start living and reproducing differently, so they evolve into two separate species, which is speciation (also known as divergent evolution). Reproductive isolation and speciation reduces gene flow.


Why is globalization potential damaging to the environment?

Protecting the environment increases production costs and reduces competitiveness.


What adaptation allows large powerful swimming fish such as a shark to be endothermic?

Isn't it something like: Vasconstriction reduces blood flow and heat transfer?


What describes a way in which urbanization can have a positive environmental impact?

Centralizing populations generally reduces the need for individual automobiles, which decreases greenhouse gas emissions.


What is the basis of inbreeding depression?

Inbreeding depression is the reduced fitness of a population caused by inbreeding. Inbreeding reduces genetic diversity, meaning populations are less genetically adaptable - and greatly increases the chances of genetic diseases and disorders. Inbreeding is most commonly associated with reduced reproductive and viability traits.


Are there any gains to smoking?

Nope. Absolutly nothing.


What are two threats to the okapi population?

Poaching for meat, and deforestation for agriculture reduces their habitat


Which breeding system reduces genetic variation in a population?

Inbreeding is a breeding system that reduces genetic variation in a population. Inbreeding occurs when closely related individuals mate, leading to an increase in homozygosity and a decrease in genetic diversity within the population. This can result in an increased prevalence of genetic disorders and reduced fitness in the population.
