HOW DOES EVOLUTION WORK?

Breeding Bunnies

This project tries to show the different genotypes for the characteristic of the fur that exists in the rabbits, and what frequency is of that each generation has this gene.

Discussion Questions
1) What was your original hypothesis?
Our original hypothesis: We think that most of them are going to have fur because the furless ones are going to be will by the cold weather. Apart from that the dominant alleles are the bunnies with fur, and the furless are recessive, so there´s more frequency of F (fur).
2) Based on your lab data, do you need to change your hypothesis? Explain.
No, we don´t need to change our hypothesis, because we have studied this topic before in Biology and we knew what was going to happen with the bunnies.
3) Compare the number of alleles for the dominant characteristic with the number of alleles for the recessive characteristic.
The number of alleles for the dominant characteristic is bigger than the number of alleles for the recessive characteristic, because the white beans died. The alleles for the dominant characteristic appeared in each generation, but the alleles for the recessive characteristic disappeared in each generation.
4) Compare the frequencies of the dominant allele to the frequencies of the recessive allele.
There are more possibilities that the individuals of the next generation are going to have fur because the dominant allele is the one with fur. So the frequencies of the bunnies with fur are higher than the ones without it.
5) In a real rabbit habitat new animals often come into the habitat (immigrate), and others leave the area (emigrate). How might emigration and immigration affect the gene frequency of F and f in this population of rabbits? How might you simulate this effect if you were to repeat this activity?
The emigration and immigration affects the frequency of alleles F and f by the fact that there are few more white rabbits, the greater the like hood that the offspring haven´t hair color. Likewise, the fewer rabbits haven´t hair in the population, either by the emigration of the same or the mass emigration of rabbits with hair, the less likely they are descendants of hairless rabbits. And the same happens with the population of rabbits whit hair.
6) How do your results compare with the class data? If significantly different, why are the different?
This point we haven´t been resolved because we make no comparison between the data obtained by us and the Class Data.
7) How are the results of this simulation an example of evolution?
Because thanks to this simulation we were able to witness how it works heredity, genetics and natural selection by observing the data and extracting conclusions.
