Quantitative Genetics Assignment

Question 1. Explain all the differences between qualitative and quantitative traits. Include specific examples to support your answer. (10 marks)

Question 2. For each of the following traits, identify if it is an example of a quantitative or qualitative traits. (5 marks)

Crop yields (g)
Crop height (cm)
Grain shape (roundness)
Flower colour (red vs white)
Animal weight (kg)

Question 3. You have been allocated a data set (see Canvas module) which represents a quantitative trait (grain weight (grams) per cob of corn) for 100 plants.

a) Using the Quantitative Genetics Workshop as a guide, create a customised histogram for your data set (insert on Page 2 of this document). (5 marks)

and;

b) Complete the table on Page 3. (15 marks)

Question 4. Two different, homozygous corn varieties were crossed together, and the resultant F₁ generation showed greater grain weight (grams)/cob of corn than either parental variety.

Why could this occur, and what would you expect to happen if the F₁ generation was used to create an F₂ generation? (5 marks)

Question 3a) Add your customised histogram of data set below. Include axes labels.

Question 3b) Table of calculations for the corn cob data set
