Analyzing and Interpreting Data

For analyzing ad interpreting data I did really well on the Tiger Breeding assignment, Mitosis/ Meiosis Graphic Organizer, and the Meiosis video explaining the key stages of Meiosis.

For example, for the Tiger Breeding assignment, we used the Minnesota Zoo program to see how genes work. The parents genes transfers down to their offspring and the purpose was to make the tiger race  resistant to disease and at the same time and to lower the inbreeding rate as much as possible. I applied my knowledge of heterozygous and homozygous and what it does to the tigers. I learned about dominant allele and recessive allele as well. Based on the result of the experiment, I wrote my reflection.

(What is your strategy for breeding disease resistant tigers?

After I finished the game the disease resistant rate was 100%, however the inbreeding rate was approximately 62% which was pretty high since I mated the same ones over and again. Then, I noticed what I did wrong. I chose one tiger that’s resistant to disease and one who’s not. I started using this strategy from the 3rd round. The inbreeding rate was 81% in the second round, however it dropped to 62%, so it worked pretty well.


How can you produce disease resistant offspring if you start with two parents who are not resistant?

Parents with gene Dd is not resistant. They are both heterozygous, and they both have an recessive allele. Since the single gene d controls resistance to the distemper virus. If the tiger carries two non-resistant alleles DD or Dd, it will not be resistant. The possibly outcome is DD, Dd, Dd, and dd. So that’s 25% of getting an offspring using¬† two non resistant parent.



Which allele is dominant and which is recessive?

Dominant alleles is dominant D, recessive in d.


How do parents who have a phenotype which is not resistant produce offspring who have a phenotype that is resistant?

If they are not resistant they have the gene type Dd. There’s 25% chance of getting an offspring who have a phenotype that is resistant since the possibly outcomes are DD, Dd, Dd, and dd.



What is a punnet square and how do you make use of it to predict outcomes of a mating?

Punnett square is a diagram that is used to predict an outcome of a particular cross or breeding experiment. It was named after Reginald C. Punnett.

If it is a match between Bb and Bb. It would create B+B, B+b, B+b, and b+b.)
