In the tomato plant (Solanum lycopersicum), the gene for stem colour (purple stem, AAA, is dominant to green stem, aaa) and the gene for leaf shape (cut leaf, BBB, is dominant to potato leaf, bbb) are located on the same autosome (autosomal linkage).
A plant heterozygous for both genes is test-crossed with a double homozygous recessive green-stemmed, potato-leafed plant (aabbaabbaabb). The diagram below shows the arrangements of alleles on the homologous chromosomes of the heterozygous parent plant:
The phenotypes of the 800 offspring produced from this cross are recorded in the table below:
| Phenotype | Number of Offspring |
|---|---|
| Purple stem, cut leaf | 364 |
| Green stem, potato leaf | 356 |
| Purple stem, potato leaf | 44 |
| Green stem, cut leaf | 36 |
