What is a null hypothesis?

A prediction where there is no real change a population

2. What is the difference between genetic drift and natural selection?

natural selection is a nature process where animals survive based on the genetic traits while genetic drift is where animals survive based on luck
3. Describe a population bottleneck and founders effect and their results.

for the population bottleneck is basically a large population is effect where a random few survive an event and founder effect is where pioneers migrate to a new place to live on

2. The difference between genetic drift and natural selection because genetic drift is when an organism survives by luck and has nothing to do with your fitness and also a lost of variation. Natural selection is when you survive out of your fitness.
3.Population bottleneck is when few organisms survive from an event whereas founders effect is when few organisms migrate to a new area.

Genetic drift is when there is a change in allele frequency by chance while natural selection is done because of a change in the environment. Population bottle neck is when some of the species survive a random event while founders is when some of the population go to a new area to populate.

Genetic drift is purely luck and natural selection is a form of evolution based on how you adapt to your environment.

The difference between genetic drift and natural selection is that genetic drfit is random and results in a change in allele frequenices. The results of genetic drift is a loss of variation. Natural selection is a natural process in which the animals who have not been able to evolve, breed, or survive start getting weeded out. Genetic drift also is different because it results into other alternatives like population bottleneck and founder effect. Population bottleneck occurs when only a few individuals survive a random event. The founder effect is when a few pioneer individuals from a species decide to move and migrate from their environment there is going to be a change in the genetic variation of the species.

A null Hypothesis is no change. Definition: The hypothesis which states experimental variables have no relationship and experimental observations are the result of chance.
2. The difference between genetic drift is the organisms get lucky it is a change in allele frequencies due to chance in a population. Natural selection is when you see if you can adapt to the change in your community.
3. Bottleneck effect: Bottleneck is when only when a few organisms survive in their community.
Founders effect: Founders effect is when a select few of organisms migrate to another community due to the circumstances. ]]> 2021-03-03 15:25:44 UTC https://padlet.com/MsLeCour/666mv95j52lo9xta/wish/1264269785 Crystal cbarkie702 https://padlet.com/MsLeCour/666mv95j52lo9xta/wish/1264272116 1•A null hypothesis is when you have a prediction that there will be no change.

2. Genetic drift is based on luck, has nothing to do with fitness and results in a loss of variation, while natural selection is based on adaptation to change, deals with fitness and if you survive natural selection means that you're fit enough to keep up with the change in the environment
