#Unit 2. Cellular Organization
Genes that share a common ancestry have similar organizations with conservation of the positions (of at least some) of the introns.
#Id: 528
The homology between two genes can be plotted in the form of a dot matrix comparison
#Id: 529
Sequences that presumably diverged as a result of gene duplication are paralogous.
#Id: 530
A gene family is defined as a group of genes that encode related or identical products as a result of gene-duplication events.
#Id: 531
Sequences that arose because of speciation are described as orthologous
#Id: 532
A mutation that confers a more advantageous phenotype to an organism, relative to individuals in the same population without the mutation, called as positive selection.
