Genetics Revision

NZ Endangered Species - generic example

1. Why is genetic diversity essential for your species

2. What is it a bottlenecked species (small species)

3. Consequences of Inbreeding Depression 

3.1 Consequences of Inbreeding depression generally (humans)

3.2 Consequences of Inbreeding depression for your species specifically

4. DNA Fingerprinting

4.1 What are microsatellites / short tandem repeats (high error rate, non-consequential, meiosis)

4.2 What are restriction enzymes (scissors)

4.3 What is PCR (photocopier)

4.4 What is Gel electrophoresis (separate by size)

5. How can DNA Fingerprinting be used for your species

5.1 how can it be used to prevent Inbreeding Depression (M) AND increase genetic diversity in your population (E)

6. Inheritance - Meiosis and Fertilization

A baby from your species is albino - homozygous recessive for a melanin mutation

6.1 Use a punnet square to prove its Normal parents must be heterozygous

6.2 Explain the formation of gametes from germ cells - follow the two alleles through this Mm (Melanin, no-melanin)

6.3 Discuss how this albino baby could grow up to have phenotypically normal children (use a punnet square and discuss dominance)

7. DNA  Sequencing. 

7.1 What is DNA sequencing (Overview of the process)

7.2 Why is it used?

7.3. How could DNA sequencing be used in reference to your species. 

8. Evolution 

8.1 Why does evolution: Survival of the Fittest + Natural selection, allow for these recessive alleles to remain in the heterozygous population?
