Shown is a picture of com kernels that Barbara McClintock us

Shown is a picture of com kernels that Barbara McClintock used to deduce the existence of transposons. If the red color kernels reflect wild type color, what caused the white kernels? Why are there red spots inside the white kernels? There are both small and larger red spots in the white kernel. What does the size of each red spot in white tell us?

Solution

Q.No 1

Transposition occured in the red kernel gene and it also disrupting its own function. Based on this new transpositions into the red kernel gene, the white dots are buried under the red cell layers.

Q.No 2

Group of cells that arose from the cell that had the transposon jump out of the red kernel gene and thus reverting it back again to being functional.

Q.No 3

The development of the transposon jumped out and the reversion back again to a function red kernel gene took place. Bigger communities of cells mean the function occurred earlier.
