Question

the trait for kernel colour in corn is controlled by how many pairs of genes??​

Answer 1

Answer:

In this article we will discuss about the inheritance of kernel colour in wheat.

Nilsson-Ehle performed many crosses between varieties of wheat having red seeds and those having white seeds. In all crosses except one the F2 generation gave a ratio of 3 red to 1 white. In the one exceptional cross he used a very old red variety from the north of Sweden.

The F1 plants produced seeds intermediate in colour between the two parents, and the F2 generation segregated in the ratio of 63 red: 1 white. The noteworthy feature of this experiment was the variation in the intensity of the red pigment in wheat grains produced by F3 plants.
