Science Homework Help

Instructions: Watch this video, and take a look at my complete worksheet download(you can find a printable version for your own use in Module 3). It is also helpful to review the exercises in your textbook. Then solve the question below. You can submit a photo or a scan, or copy and paste into the submission area from a word document. I hope these links work.

QUESTION: Now that we know the genotype for both Santiago and his father for PTC tasting, can we find out Ernesto’s genotype for sure?

Note: Here is what we know: Ernesto CAN taste PTC, so his genotype is either TT or Tt. We know that Santiago (Ernesto’s half brother) CAN NOT taste PTC, so his genotype is tt. We also know that the father of both boys CAN taste PTC, so his genotype is Tt.

Here is what we do NOT know: whether Ernesto’s mother can taste PTC or not.

Assignment. Draw/create squares that show the possibilities for Ernesto’s genotype. You will likely need at least two or three squares to show all possibilities. Put his father’s genotype on one axis, and possibilities for his mother on the other axis. Show the various ways Ernesto could end up with EITHER TT or Tt.

and here is one on sex-linked traits.
