An introduction to Genetics

 Watch the introduction to Genetics video and make notes on it. You may use the notes organizer I provided in class called "The analogy of shoes". Please make a correction on the student notes.  Where it says "boy" cross it out and put XY .  Where it says girl, cross that out and put XX.  These are chromosomes for individuals. Note that XY individuals have testes which produce sperm and XX individuals have ovaries which produce eggs.  

The term "boy" and "girl" refers to gender identity and this identity can be for an individual who has XX or XY chromosomes.

Today we explored fetal circulation.  First we drew our conception of how fetal circulation might occur. Next we compared fetal and baby circulation in depth in the table below.  Finally we drew a schematic diagram to compare the two and listened to a baby cry because the newborn's first breath is when the ductus arterioles and the foramen ovale closes successfully
