What effect do mutations have on a population's genetic variation
Mutation is the sudden change in the DNA. Mutations change the sequence of the DNA. When the sequence of the DNA is changed then mRNA made will also be faulty. This mRNA will further make a faulty protein. This faulty protein will perform some or the other function in the human body. This faulty protein might provide an advantage to the individual or might cause a problem.
So, in this way mutation causes variations in the genome of the organisms.
Genetic changes caused by mutations can have the following outcome(s) on the phenotype of an individual_______________ Answer choices: A) no effect on the fitness B) increases fitness C) all of the above D) reduces fitness
Transposons are found in every genome we have looked at so far and give genetic variation (mutations) to the host cell by O A. Taking in naked DNA O B. Binding to RNA OC. Interfering with transcription OD. moving parts of chromosomes around Reset Selection
17. Most randomly occurring mutations that occur in humans do not have an effect on phenotype. Why is this? (4 points)
What is responsible for genetic variation in bacteria? O gene influx from a different bacterial strain Ogene transfer from the same bacterial species O mutations in the genome during binary fission ODNA influx from the environment All of the options
O c. Mutations are the ultimate source of genetic variation d. More individuals are born than will survive. e. Individuals that possess the most favorable variations have the best chance of reproducing. en 44 If the bacterium Mycobacterium tuberculosis experiences a significant cost for maintaining a specific antibiotic-resistance gene, what would you expect to happen in environments that lack that antibiotic? answered Out of 2.00 question Select one: a. Bacteria with the resistance gene would try to make the cost...
1. Genetic drift is an important mechanism for maintaining genetic variation in populations. True False 2. According to several studies (e.g., bacteriophage f1), most mutation are _______. A. lethal B. deleterious but not lethal C. approximately neutral D. beneficial 3. Most mutations occur in response to the adaptive needs of the organism. True False Can please answer all 3 questions ASAP. Thank you in advance!
Why are mutations essential to biological variation? And why is variation important?
a) Why do species that reproduce sexually have more genetic variation than species that reproduce asexually? b) Why is it difficult to use genetics to predict exactly how tall someone will be? c) Many prokaryotes reproduce asexually using binary fission. Why is it impossible for a prokaryote to use the process of meiosis for reproduction? d) Monosomy is a genetic disorder. In this disorder, a person receives one gamete that has is missing a chromosome. This gives the person one...
Genetic variation in a population refers to which of the following? Group of answer choices a) Multiple individuals breeding together b) Multiple alleles within a genepool c) Multiple phenotypes with the same genotype d) Multiple genes within a genome e) Multiple offspring with advantageous mutations
Within populations Between populations Increase genetic variation Decrease genetic variation Answer Bank migration genetic drift mutation some types of natural selection
