Indian Corn Lab and a sunflower!

In Genetics this morning, after some Mendelian genetic review, we started our Indian Corn Dihybrid cross lab.  Studying ears of Indian Corn with two characteristics ... purple (dominant) and yellow kernels with starchy dominant over sugary (wrinkled) kernals.  For each ear, we tried to determine the phenotypic ratio and the parent cross that produced the kernels. Tomorrow, we will run a Chi Square analysis of our results to determine the validity of the data.

The Selected Topics class worked on the same lab but a different version.  We will analyze group data tomorrow and start to wrap up our study of genetics with a survey of human diseases and conditions.

Today was our second day of programming in Microsoft qBASIC.  We are already working on if-then and if-then-else statements in addition to counters and For/Next looping statements.

After school, we got a good rain of about an inch ... great on our Uncle Burl Broughton Turnip patch.  The turnips have already germinated and the biggest plants are about the size of a quarter.  Also, before the rain took a picture of one of our best sunflowers.  Website below shows the fibonacci number of the seed patterns ...
