(A) The total number of seedlings is $209 + 14 = 223$.The ratio of green to white seedlings is approximately $209/14 \approx 14.93 : 1$,which is very close to the $15 : 1$ ratio.$A$ $15 : 1$ phenotypic ratio is characteristic of duplicate gene interaction (also known as duplicate recessive epistasis),where the presence of at least one dominant allele at either of the two gene loci results in the dominant phenotype (green).Therefore,the parent plant must have been heterozygous for two duplicate genes (genotype $AaBb$).

In wheat,when a green plant was self-fertilized,the progeny had $209$ green seedlings and $14$ white seedlings. The above result indicates that:
