Solutions For An Introduction to Genetic Analysis Chapter 6 Problem 32P

Step-by-Step Solution

Solution 1

In roses, the synthesis of red pigment is by two steps in the following pathway:

a) Colorless flowers would be produced since the colorless intermediate would not be processed any further.

b) The flowers would attain a magenta color as through the action of the gene P product the colorless intermediate would be converted to magenta intermediate giving its prospective color.

Step #3 of 5

c) For null mutations in both p and q genes, the flower of the plant would remain white or colorless as the white intermediate would remain without any further processing.

Step #4 of 5

d) p/p; Q/Q - null mutation in p gene

P/P; q/q - null mutation in q gene

p/p; q/q - null mutation in both p and q genes

Step #5 of 5
