Which of the following statements explains genetic variation? Genetic variation arises ____.     When organisms need to change to survive in a new environment.     From environmental changes that affect organisms.     Through mutation and sexual reproduction.     From traits acquired during the lifetime of an organism.

Give typing answer with explanation and conclusion to all parts

All the genetic variation seen in the human population, passed from generation to generation, arose from mutations that occurred in.. O Somatic (body) cells Reproductive cells (eggs and sperm)

1.

A mutant in a population represents a _______. The answer is not a mutation or new species. So I’m not really sure what it could be?

What are the properties of genetic material? Must encode information. The information must be used to direct the functioning of cellular processes. The information must be transmissible from generation to generation and from cell to cell. There must be the potential for mutation that can result in the physical variation that exists among individuals and between species. All the above are correct.

A common misconception about mutations is that they are always harmful. What is the reality of mutation effects on an organism? O Mutations can be harmful, neutral, or beneficial, and they drive genetic variation Mutations are always harmful and decrease genetic variation Mutations are always neutral and have no effect on genetic variation Mutations are always beneficial and increase genetic variation

I need help with a biology question: Sometimes a restriction in genetic variability is imposed on populations by natural catastrophes such as flooding, earthquake, etc. The surviving individuals reflect only a small, random genetic sample of the population affected. This process is termed    sudden mutation the founder effect non random mating gene flow

Genetic diversity 1. Why do multicellular organisms have two copies (alleles) of any given gene? 2. What genotype(s) will result in a dominant phenotype, and why? 3. What genotypes(s) will result in a recessive phenotype, and why? 4. What do mean by the “gene pool” of a population? And why is this such an important concept inunderstanding how evolution works on small scales?5. If p = 0.75, what does q equal? And how do you know this? 6. What does it mean to say that a population has been become “fixed” for a particular trait? Whatvalues for p or q tell us that fixation has occurred? 7. Ultimately, why are we concerned about the loss of genetic diversity (i.e., fixation)? 8. Contrast natural selection with genetic drift. Which one is always adaptive? Explain your answer. 9. What’s the bottleneck effect? Describe some examples of organisms that have experienced this &what caused it to occur. 10. How can gene flow help to restore variation that may have been lost through bottleneck…
