what would happen if a mutation created a new allele that decreased fitness?course hero

The new allele would have a negative effect on the fitness of the individual who carried it, resulting in that individual having few or no children. In the event that a mutation occurs in one’s DNA, what happens? It is possible for changes in the DNA sequence of a gene to cause changes in the protein the gene codes for.

How is artificial selection different from natural selection Quizlet?

In what way is artificial selection different from natural selection? In artificial selection, human preference is the selecting force; in natural selection, environmental conditions are the selecting force. When a population of organisms is evolving, what can you be sure is happening? Nice work! You just studied 32 terms!

Why is the genetic code Universal Quizlet?

**The genetic code is universal, which means that all organisms use the same codons to code for the same amino acids. The universality of the genetic code means that a human gene can be produced in bacteria Nice work! You just studied 108 terms! Now up your study game with Learn mode.

Is the squirrel trait an adaptation of natural selection?

The trait is only an adaptation if it gives the squirrels an advantage in their habitat. If you wanted to see natural selection working in a population of mosquitoes in response to pesticide, how much pesticide should you use? Enough to kill most but not all the mosquitoes.

What happens when a mutation changes the first nucleotide of a template DNA strand from AAG?

A mutation changes the first nucleotide of a template DNA strand from AAG to TAG. This causes the mRNA codon produced to change from UUC to AUC. Which anticodon would bind to the mutated codon?

How to clone a gene into a bacterial cell?

Put these steps (required to clone a gene into a bacterial cell) in the correct order: 1. A restriction enzyme is used to cut open the plasmid. 2. The recombinant plasmid is inserted into a bacterial cell. 3. The gene is incorporated into the plasmid. 4. Protein production occurs. 5. A restriction enzyme is used to cut out the gene of interest.

Is special creation a scientific hypothesis?

True or false: Special creation is NOT considered a scientific hypothesis because no one has ever tested it using scientific means.

Do bacteria and humans use the same genetic code to produce proteins?

Bacteria and humans use the same genetic code to produce proteins.

Is a bat's wings homologous?

Bat wings are homologous to the front legs of cats. What does the term "homologous" mean in this context?
