Question

The purple colour results from the formation of a purple pigment in the skin of the kernel. The gene locus for the colour trait is designated “R”. The wrinkled phenotype arises from a decrease in the amount starch produced within the kernel. The gene locus for the texture trait is designated “S”.

Present the data as monohybrids (Xx, XX, xx) for all five corn cobs and
for the plant. Present the colour and texture phenotypes with their associated genotypes in separate tables.
 Your first table should include the corn ID, the number of purple kernels, the number of yellow kernels, and the phenotypic ratio between the two kernel colours.
 Present the texture results in the same format to a separate table.

What is the dominant phenotype for kernel colour in your assigned corn
plant? What is the dominant phenotype for kernel texture in your assigned cornplant?
