Making Babies Activity II: Understanding rules of inheritance for several traits, while considering alignment, crossover, sex-linkage and lethal genes.
GenScope File: MakingBabies.gs
Start off by double-clicking on the Making Babies file. This will automatically start up GenScope with two dragons, Wilma & Fred, already showing. OK, now you're going to try to make babies of various kinds but this time you will control which way the chromosomes go.
Remember that to make a baby you have
to start with a cell from the mother and a cell from the father (use the
cell tool -the one that looks like a little circle -and click on a dragon).
Then you run meiosis to make the gametes (the four little cells that carry
the baby's chromosomes) and drag one gamete from the mother (on the left)
and one from the father (on the right) into the middle window. Then you
run fertilization and the two gametes (an egg from the mother and a sperm
from the father) come together to make the baby.
1. Make a boy dragon with no horns, wings, and two legs.
See if you can make a female, firebreathing dragon.
4. Can you make a bronze dragon with horns, no wings, and no legs? No hints on this one. We'll just tell you this: it is possible -and if you can do it you're a very good geneticist. Congratulations!
