<\/a><\/p>\nHere is the complicated six sibling comparison:<\/p>\n
In this comparison, Jim is V, Jon is F, and Joel is D. V&F, V&D and F&D correspond to my three brother comparison above. My three sisters have two X Chromosomes, so they have a maternal and paternal side. The paternal side is the same for all three sisters, so they are at least half identical in all places. Yellow is the half identical areas. Red is no match and green means that my sisters match on both the maternal and paternal sides.<\/p>\n I have set the crossover points here:<\/p>\n Next I need to figure out who owns each crossover. It looks like the first one belongs to Heidi:<\/p>\n Every time there is a change in one of the comparisons, Heidi is involved. In three sibling visual phasing, Heidi would be involved in match changes with two other siblings. In six sibling visual phasing, she shows the changes with each of her five siblings. This gives more certainty to setting crossover lines.<\/p>\n I tried to build the chromosomes a second time without all the added cousins as that was slowing the process down. The spreadsheet allows you to add them later. Here is the assuring message I got:<\/p>\n I can add the cousins in later.<\/p>\n Note that at about position 23, it appears that Jim should have a crossover, but it actually goes to his two brothers:<\/p>\n This is a little easier to see in the six sibling comparison:<\/p>\n Jon (F) is in purple and Joel (D) is in orange. These two crossovers are not in the same place but are very close to each other. Joel’s is first at about 23M and Jon is next at about 23.3M.<\/p>\n Here Jim’s crossover is at 87.5M and Lori’s is at 87.7M. That means I need to add another Line for Lori. Now I have 13 crossovers for six siblings:<\/p>\n I would like to add cousins to the spreadsheet, as I took them out earlier to make the spreadsheet build run smoothly. Now I will add them back in. I went through Steve Fox’s instruction manual. I added back in cousins and hit the ‘add’ button. I had added my father’s cousin Jim and the program didn’t like that as my brother is also Jim, so I changed my father’s cousin’s name to James and the program was happy. I added 17 cousins, so it could take the spreadsheet a while to add in 17 cousins for 6 siblings. Based on the progress, this process should take about an hour if nothing times out. Actually, it did time out or Excel hung up and I wasn’t happy with the results. So I deleted the cousins and added them in in two batches after closing unneeded programs and Excel spreadsheets.<\/p>\n Here is another assuring announcement:<\/p>\n After this, I ran the other 9 cousins and I successfully completed the build.\u00a0This build process took a while but should be well worth it.<\/p>\n Heidi, Sharon, and Lori will all have their X DNA from their paternal grandmother – Frazer.<\/p>\n I put Frazer on the bottom. That means the maternal side will go on top. For that, I just need to see a few cousin matches. When I choose ‘all cousins’, I see that Anita and her sister have the best X Chromosome matches with my family:<\/p>\n Anita matches Jim, Sharon, Heidi, and Lori on the right. Anita has smaller matches near the middle of the Chromosome with Sharon and Lori . By comparing the chromosomes on the right, it looks like I can see a crossover for Sharon (at 68M) and Lori. For some reason, the position numbers for the matching comparisons are not all showing at the left.<\/p>\n Remember, I said that Lori had a crossover on the right hand side? It shows as my crossover (D or Joel). That means I probably missed a crossover for Lori.<\/p>\n Here is a comparison between Lori and Jim that shows where Lori’s crossover is:<\/p>\n Every carat mark is one million, so Lori’s crossover is at 142M.<\/p>\n Anita above represents Rathfelder, so I just need to put in Rathfelder everwhere that Anita matches my family.<\/p>\n The spreadsheet has a function called Extend, but it didn’t work for the Rathfelder entries for some reason. I’ll just extend Rathfelder manually to the crossovers:<\/p>\n I extended Jim, but ran into a problem with Sharon:<\/p>\n If I extend Sharon to the right, it goes through a crossover line. A crossover line is where there should be a change from Rathfelder to Lentz. That means that something is wrong. I’ll just visually phase the brothers:<\/p>\n Then I will go segment by segment from Jim to his sisters to see where the change is needed.<\/p>\n It turns out that I was doing it right, but the two small matches with Anita and Inese were wrong. The common wisdom is to ignore X Chromosome matches under 15 or 20 cM. In my opinion, this is especially true between two females. I find this a bit confusing as three cousins match on those two segments of Sharon and Lori.<\/p>\n So that was supposed to be the ‘easy’ Chromosome!<\/p>\n Here is another way of looking at the X Chromosome and cousin match:<\/p>\n Jim (V) matches Lori and Sharon at segment S-F as shown by the blue bars above. Sharon and Lori match cousins Anita, Inese and Catherine at the same segment. However, James does not match cousins Anita, Inese or Catherine at the same segment. That is further confirmation that the X Chromosome match Anita has with Lori and Sharon is not good for use in Visual Phasing.<\/p>\n The Fox Spreadsheet also has a Segment Map. This is a check to see if your final results match up with the original Gedmatch comparison. It is not a proof that the visual phasing is right. However, if it does not match, it is pretty good proof that something went wrong.<\/p>\n For the X Chromosome, it only works for the three sisters.<\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\nSecond Try at Building the Chromosomes<\/h3>\n
