Help with Mendelian Genetic Inheritance Lab
I have a lab where I grew several seeds in Petri Dishes in order to study the inheritance of phenotypes. I need to make Punnets squares with the data I gathered and fill in the chart below. I understand the general idea of the Punnets square but am lost with creating it. I also am not too certain how to do the F2 generation prediction and F2 percentage prediction in the second chart. I am certain I can do the P1 generation %, F1 Generation%, and F2 Generation percentage actual. Not sure if it matters but I started with 10 – P1 seeds but only 9 sprouted, and 40- F2 generation seeds but only 37 sprouted.
Genetic Inheritance Data Table
Number of plants with: | P1 Generation | P1 Generation Percentage | F1 Generation | F1 Generation Percentage |
Purple Stem and Yellow-Green Leaves | 2 | 4 | ||
Purple Stem and non-yellow green leaves | 7 | 6 | ||
Non-purple stem and yellow-green leaves | 0 | 0 | ||
Non-purple stem and non-yellow-green leaves | 0 | 0 | ||
Total number of plants | 9 | 10 |
F2 Genetic Inheritance Data Table
Number of plants with: | F2 Generation Prediction | F2 Generation Percentage prediction | F2 Generation Actual | F2 Generation Percentage Actual |
Purple Stem and Yellow-Green Leaves | 12 | |||
Purple Stem and non-yellow green leaves | 8 | |||
Non-purple stem and yellow-green leaves | 17 | |||
Non-purple stem and non-yellow-green leaves | 0 | |||
Total number of plants | 37 |
