How to identify paternal or maternal side of a pair of chromosome?

Question

On the graphics of the Chromosome Browser of FTDNA, or the one from Gedmatch, is there anyway to identify which side of the pair of chromosome is paternal or maternal?

Comments

You can use segment matching to analyse paternal and maternal segments and so build up a painting of each side of the chromosome. Take a look at the DNA Painter tool.

Answer 1

With a single DNA sample, no you can't determine which came from which side. Chromosomes aren't tagged as to which side they came from. If you have additional DNA samples, you can start to do that. In Chromosome mapping it is best to have 3 siblings DNA to build the genome of the grandparents. Adding first cousins into the mix can allow sorting out sides.

Answer 2

Keep in mind that DNA segments can exhange between a pair of chromosomes.
