This question is from a genetics session in my university:
The test cross between a plant with smooth and yellow seeds and a plant with wrinkled and green seeds gives the following results: 140 plants with smooth and green seeds, and 142 plants with wrinkled and yellow seeds. These results are consistent with which case of the following?
- Linked genes
- Epistatic genes
- Genes with intermediate dominance
- Genes with complete dominance and independent assortment
In my answer key the correct choice is linked genes.
What I know is that in the case of linked genes, the outcomes are: either all parental (complete linkage) or the majority of offspring have parental traits and we have few recombinants(partial linkage).
But here it seems like all offspring are recombinants?! How can this be? Is there a mistake in the question, in the answer, or in my information?
Any help is appreciated. Thank you.
