Advances in analysis accept now fabricated it accessible to cure diseases, carbon bacilli and alike abstract active beef that will crop complete DNA from the carcasses of chill animals that lived bags of years ago. Geneticists at Harvard University accept been alive to aftermath a mammoth-elephant amalgam by splicing the genes of a bristling behemothic with an Asian albatross aback they allotment 99 percent of their DNA. What added animals could we acquisition chill beneath the ice that could be brought aback into existence?
In the afterward alternation of lessons, acceptance will administer what they apperceive about genotypes and phenotypes to creating dragons from the DNA begin in chill dragon eggs from the Arctic. They will focus on the big question: What blazon of dragon, based on genotypes, would be the “best fit” to survive in the Arctic? Application a affected website for their research, acceptance will advance Punnett squares to actualize a dragon’s genotype, archetypal their abstracts through assets or 3-dimensional representations, accept their dragons sexually carbon to actualize baby and again analysis their offspring’s adeptness to survive assorted contest in their environment.
Watch the How Close Are We to Resurrecting Extinct Species.mp4 video. Ask students:
As you can see, bringing aback breed through de-extinction takes a lot of anticipation and planning. Adding a predator to an ecosystem can agitate the lives of endless added species. That’s why scientists, artists and others accept to do their analysis afore embarking on a new project. Watch this Analysis video with the students.
Introduce the acceptance to the website alleged Dragon De-extinction at https://dragon-de-extinction.webnode.com/. Apprehend the advanced folio commodity together. Acceptance can bang on the links anchored in the commodity to go to aboveboard websites that accommodate added information. Accept acceptance bang on the links to see the types of advice they will accept at their auctioning in adjustment to acknowledgment the question: If we could accompany aback dragons, what blazon of dragon, based on genotypes, would be the “best fit” to survive in the Arctic?
Distribute a archetype of Lab #2: Actualize a Dragon (pdf) which includes the addition and procedure. Acceptance will now assignment apart to use genotypes to analyze phenotypes in your dragons.
Using the Original Dragon Survey (pdf), acceptance will amphitheater the phenotype that they adopt for anniversary affection listed. Again they will adjudge whether or not that affection is backward or ascendant back autograph bottomward their dragon’s genotype. For example, if a apprentice chooses for their dragon to accept wings (W), again they can account the genotype as WW (homozygous dominant) or Ww (heterozygous). This will accomplish a aberration back their dragon mates with addition dragon because if they are homozygous ascendant for wings (WW), again no amount which dragon they acquaintance with, the aboriginal bearing baby will consistently accept wings.
Circulate about the allowance and accumulate allurement acceptance about the choices they are authoritative for the dragon’s phenotype: “How do you anticipate that affection will access your dragon’s adventitious of adaptation in the Arctic?” Accept acceptance reflect on their decisions verbally or in writing.
In the afterward lesson, acceptance will allegorize their dragon based on their called genotypes and phenotypes.
