What does not add new alleles to a population gene pool?
1.Which does not add new alleles to a population gene pool?
What are 3 causes of variation within a population?
Changes within a gene pool occurring from generation to generation is called microevolution. Allele frequencies in a population may change due to gene flow, genetic drift, natural selection and mutation. These are referred to as the four fundamental forces of evolution. Only mutation can create new genetic variation...the other three forces simply rearrange this variation within and among populations.
How have genetic engineers increased the effectiveness of tnf?
Genetic engineers developed a way to add the gene encoding TNF to a kind of white blood cell that is effective at locating cancer cells but not effective at harming them.
What is difference between DNA and genes?
A gene is a section of DNA that will eventually code for a specific protein. All genes are composed of DNA but not all DNA are genes. or It is a name given to some stretches of DNA and RNA that code for a polypeptide. or A gene is a segment of DNA that will transcript for a specific protein.
Why is evolution difficult in a laboratory?
Evolution is quite easy in a lab. All you need is some bacteria and something that those bacteria are killed by. Add a small amount of each to a clean slide, and you can watch as the population declines - as weaker members die - before growing again - as the stronger ones reproduce. Now add more of the toxic chemical, and repeat the experiment. Keep going, and eventually you get a population that not only survives in the toxin, but thrives in it.

Why must allele frequencies in a gene pool always add up to 100 percent?
To maintain genetic diversity.
Are mutations the only way to add new genes to a gene pool?
yes. independent assortment and crossing over in mitosis will add new combinations of alleles to the DNA but only mutations will create new genes.
How can you add ADD a GENE to your genome?
yes
How do you lower chlorine level in pool?
You add water to the pool
How do you convert a saltwater pool to a chlorinated pool?
Add alot of iodine
When do you add DE to a pool?
You add D.E. to a pool when you do a fresh filter clean. You also add D.E. if you have to backwash your pool more than normal. When you backwash the pool it is also dumping the D.E. out so it needs to be replaced to keep the grids covered so the pool can filter properly. Hope it helped
When do you add clearifier after shocking pool?
Yes you can add shock solution to your swimming pool after or at the same time as a clarifyer. You should not swim in your pool for at 4 hours after shocking it.
What pool chemicals do I add to restore balance to the pH of the pool?
To raise the pH of your pool you add soda ash (sodium carbonate). To lower the pH of your pool add muriatic acid (hydrochloric acid) or sodium bisulfate. You should always add chemicals with the pump running and check your levels again once the newly added chemicals have been circulated around the pool.
How do you convert a fresh water pool to a salt water pool?
Add salt
