Mark Orwig is the writer of the Genealogy Explained website, and he has created a neat graphic to explain the answer to the question posed in "Do Siblings Have the Same DNA?" I encourage all of my readers to read the entire article because the science is interesting and the "deck of cards" example is familiar to most of us. The graphic is: Pictures are always better than many words, and this graphic shows why siblings (assuming they aren't identical twins) may not have the same ethnicity estimate even though they have the same parents. In the graphic, there are four grandparents who have perceived ethnicities of: * Paternal grandfather: 50% Scottish, 50% Irish * Paternal grandmother: 100% Italian * Maternal grandfather: 100% German * Maternal grandmother: 50% Italian, 50% Irish Based on the percentages, one would expect the ethnicities of the parents to be: * Father: 50% Italian, 25% Scottish, 25% Irish * Mother: 50% German, 25% Italian, 25% Irish Based on those percentages, one would expect the ethnicity of a child to be: * 37.5% Italian, 25% German, 25% Irish, 12.5% Scottish. However, the graphic shows that the two children have significantly different ethnicity estimates (based on a DNA test) than the expected ethnicity based on the expected ethnicity of the parents. This occurs because of the random nature of admixture - how the DNA segments are passed down to the next generation. For me, I have noted that the six different ethnicity estimates I have received are completely different, and do not match my perceived ethnicity based on classical genealogy research. See Comparison of My Autosomal DNA Ethnicity Estimates. I understand better now that I need to test my two brothers and both of my daughters to get a better handle on the ethnicity estimates for my family members. Unfortunately, I did not have the opportunity to test my parents (who died in 1983 and 2002) and grandparents (who died in 1942, 1962, 1976, 1977). Like I said - Read the entire post! Thank you to Mark for permitting me to use the graphic in this blog post. ============================================== The URL for this post is: http://www.geneamusings.com/2018/07/genealogy-explained-do-siblings-have.html Copyright (c) 2018, Randall J.

Humans don't "own" their own genes, the cellular chemicals that define who they are and what diseases they might be at risk for. Through more than 40,000 patents on DNA molecules, companies have essentially claimed the entire human genome for profit, report two researchers who analyzed the patents on human DNA. Their study raises an alarm about the loss of individual "genomic liberty."

Beyond Science: How to Talk to Your DNA by Michelle Walling, CHLC Our DNA holds the secrets of immortality and wellness. Within it lies the wisdom of not only our genetic ancestors but our past and future life experiences as well. We have been told that we will be activating ten strands of dormant 'junk' DNA that are overlaid in the two active strands of DNA that we currently operate with. How can we activate this extra DNA in order to access the wisdom needed to move forward? What is DNA? DNA lies in the nucleus of each cell in our body except for red blood cells. The blood in the body carries DNA but only in the white blood cells of the blood since red blood cells do not have nuclei. The instructions for the blueprint of our human body is replicated in full in each nucleus. In essence our body is one large hologram with each cell containing a complete pattern of DNA and all cells make up the whole of our physical existence. Besides serving as a template, DNA serves as a place to…
