What explanation does science give about how the Mouflon found on an island in the Indian Ocean were able to maintain their genetic diversity under extraordinary circumstances?

Dr. David Coltman, an evolutionary geneticist at the University of Alberta, says that although the models of genetic drift predict the genetic diversity of the Mouflon should have been lost over time. The genetic diversity of the Mouflon has been maintained because "natural selection is more important to the evolutionary process than is commonly believed," according to Dr. Coltman. The extreme conditions of the island are thought to have prevented genetic drift because of the premium advantage the more genetically diverse mouflon on the island hold over their less genetically diverse cousins.

Science suggests that the Mouflon population on the island likely maintained genetic diversity through a phenomenon known as the founder effect. This occurs when a small group of individuals establishes a new population, carrying only a fraction of the original gene pool. Over time, mutations and natural selection can contribute to genetic diversity, ensuring the survival of the population despite starting with limited genetic variation.

What are two ways that sexual reproduction helps create and and maintain genetic diversity?
Sexual reproduction helps create and maintain genetic diversity by: # The independent assortment of chromosomes during meiosis. # The random fertilization of gametes.
Why must allele frequencies in a gene pool always add up to 100 percent?
To maintain genetic diversity.
Why do alligators and wolves help maintain biological diversity?
Alligators and wolves help maintain biological diversity by acting as top predators in their ecosystems. They regulate prey populations, prevent one species from dominating the ecosystem, and create a balance that allows for a greater variety of species to coexist. Their presence contributes to a healthier and more dynamic ecosystem overall.
How does gametes contribute to the ability of the organism to maintain homeostasis?
Gametes are involved in sexual reproduction, which increases genetic diversity and adaptability within a population. This genetic diversity allows the organism to better respond to changing environmental conditions, thus contributing to the overall maintenance of homeostasis through adaptation.
What is the purpose of having redundancy and diversity in nuclear reactors?
Having redundancy and diversity in nuclear reactors helps to improve safety and minimize the risk of accidents. Redundancy ensures that critical systems have backups in case of failures, while diversity involves using different designs or technologies to provide additional layers of protection. This helps to maintain the integrity of the reactor and prevent the potential for catastrophic events.
What are emergency powers?
Extraordinary powers given to a government in extreme circumstances. Such powers allow them to bypasses normal rules, laws, and requirements of whatever regime they exist in. Such powers are usually used to maintain control in an area during an emergency.
Can you inbreed mice?
yes if you dont maintain genetic diversity
For what were bears born?
To eat, and to maintain ecological diversity in its habitat.
What are two ways that sexual reproduction helps create and and maintain genetic diversity?
Sexual reproduction helps create and maintain genetic diversity by: # The independent assortment of chromosomes during meiosis. # The random fertilization of gametes.
What is the significance of the movement of genes from one organism to another?
The movement of genes from one organism to another can result in genetic diversity and allow for the transfer of advantageous traits. This process, known as horizontal gene transfer, can facilitate adaptation to new environments, contribute to evolution, and sometimes lead to the spread of antibiotic resistance in bacteria.
What is the meaning of the line If you can keep your head when all about you are losing theirs?
If you can maintain control of yourself and your emotions when in dangerous or confusing circumstances when everyone else in those circumstances with you is unable to maintain control of himself and his emotions...
Why must allele frequencies in a gene pool always add up to 100 percent?
To maintain genetic diversity.
Is data reliable?
In general, reliability (systemic def.) is the ability of a person or system to perform and maintain its functions in routine circumstances, as well as hostile or unexpected circumstances.
What is product reliability?
In general, reliability (systemic def.) is the ability of a person or system to perform and maintain its functions in routine circumstances, as well as hostile or unexpected circumstances.
How do eurpeans protect the diversity of langugages?
By allowing each state to maintain its own identity. They did this by protecting the borders and languages of its union.
What are benefits of preserving languages?
Preserving languages helps maintain cultural diversity, promote intergenerational communication, and preserve traditional knowledge and customs. Additionally, it can contribute to the understanding of human cognition and linguistic diversity in the world.
What word have the same meaning as persevere?
determination; maintain a course of action; failure to stop implementation of present circumstances
