For extra credit, Can you figure out a way using a Punnet Square that the daughter could look like her mom if they were both hairless and the dad had hair? Most of you answered that the mom must have the dominant allele but that is not necessarily the case. We went over this during office hours so if you attended, you are still eligible for the extra credit. Draw a punnet square and explain:)
Notice the horizontal line between the parents. Mom (circle) is colored in because she is a PTC taster. Dad (square) not colored in, and doesn’t taste PTC. There is one vertical line going from parents to the horizontal line for the offspring. The five children 3 females and 2 males. Only on female and 1 male are PTC tasters so they are colored in. (Thank you, Angelina!)
This got deleted. Sorry things are out of order. Thank You Shiloh!
If you can’t find your own flower to dissect this week you can use these images that I took at Hendrick’s Park and create your drawings from these.
Remember our studies from IC3 that the body needs oxygen in order to be able to do a chemical reaction called Cellular Respiration (Glucose + Oxygen -> Water + CO2) so that we can use the food we eat for energy to do all the things our body does? We studied the anatomy involved in the air coming in through our nose and mouth to our lungs, passing through the alveoli to the red blood cells in our capillaries and traveling out through the circulatory system to our body’s cells. That background information will help you understand the science of Coronavirus infections discussed in the video linked above.
