Identify the phenotypic ratio of Duplicate gene action.
Answer & Solution
Correct Answer:
Option
B
The phenotypic ratio of Duplicate gene action is 15 : 1.
In this cross, whenever a dominant allele is present at either locus, the biochemical conversion occurs, and a coloured kernel results.
Thus, only the double homozygous recessive genotype produces a phenotype with no colour, and the resulting phenotypic ratio of colour to noncolour is 15 : 1.
