In a flowering plant species, there are only two characters for which contrasting traits are present in the population and these genes are on different chromosomes. If we randomly select a seed from a heap of seeds produced by dihybrid individuals of this population, What would be the probability that the plant produced by this seed would have one dominant and one recessive trait?

Many of the genes, although they are linked get separated in the coming generations. This is due to
| 1. | Independent assortment of chromosomes |
| 2. | Occurrence of two or more alleles of a gene |
| 3. | Crossing over during reduction division |
| 4. | Their presence on the same locus of the sister chromatids |
