Difference Between Linked Genes and Unlinked Genes.

The main differences between Linked Genes and Unlinked Genes are as follows.

LINKED GENES  UNLINKED GENES
1. These genes are placed very closely on the chromosome and do not show independent assortment at the time of gamete formation. These genes are located distantly and undergo assortment(segregation)
2. They show dihybrid ratio of 3:1 Show dihybrid ratio of 9:3:3:1
3. In Dihybrid cross, they show test cross ratio of 1:1. Show test cross ratio of 1:1:1:1
