Summary Introduction

To explain:

How the number of genes that influence a polygenic trait can be determined.

Introduction:

Polygenic inheritance is an exception to Mendel’s laws. Polygenic traits have wide variation in them and these traits are regulated by more than one gene. Height is an example of a polygenic trait, which is controlled by three genes having six alleles. If a person is dominant in all the alleles, then height would be very tall. Another example of polygenic trait is skin color in people.

13. Practice Calculations: 3 colonies were suspended in the following dilution series and then a viable plate count and microscope count was performed. Calculate IDF's, TDF's and then calculate the CFU/mL in each tube by both methods. Finally calculate the cells in 1 colony by both methods. Show all of your calculations in the space provided on the following pages. 3 colonies 56 cells 10 μL 10 μL 100 μL 500 με m OS A B D 5.0 mL 990 με 990 με 900 με 500 μL EN 2 100 με 100 μL 118 colonies 12 colonies
