You have figured out that it's normal for siblings to show different ethnicity percentages, but now you want to understand why. In this post, I will explain how this happens, and why it's actually a huge benefit to you that your sibling has DNA that doesn't match yours.

In the State (country) of Israel is DNA testing illegal?

It’s not true that DNA testing is completely illegal in Israel — but it is highly regulated. Here’s what the laws and practice say, and the limits that exist. If you want, I can send you the relevant passages of law in Hebrew + English.



What the Law Says
1. Genetic Information Law (2000)
• There is a national law (Genetic Information Law, passed in 2000) that governs how genetic testing is conducted, what kinds of tests are allowed, and who may conduct them. 
• Among other things, the law requires that DNA/genetic testing (particularly for family ties, etc.) be done only by licensed laboratories or institutes approved by the Ministry of Health. 
2. Paternity / Family Relationship Tests
• These are very tightly regulated. A test to establish paternity or other familial relationship generally requires a court order (usually from the Family Court). Even if all parties agree, you can’t just do it informally for legal purposes. 
• The results of the test are submitted to the court; in many cases they are not released to the tested persons directly. 
3. Genetic Screening for Medical / Health / Preventive Purposes
• These are more permissible. For example, the Ministry of Health operates programs for carrier screening for hereditary diseases, prenatal genetic screening, etc., subject to informed consent, ethical rules etc. These are widely in use. 
4. Direct-to-Consumer (DTC) / At-Home Ancestry / Genealogy Kits
• Sale and use of direct-to-consumer genetic ancestry / home DNA test kits face significant restrictions. For example, some companies do not offer their kits for sale to residents of Israel because of legal/regulatory issues. 
• The law requires that DNA/genetic testing for familial relationship / paternity etc. be done under court order and by approved labs. Tests conducted abroad or by non-approved labs may not be recognized for legal status (e.g., citizenship, family law). 



What’s Not True / What Is Misunderstood
• There is a rumor that all DNA testing is illegal in Israel. That’s false. 
• DNA testing for medical diagnoses, ancestry interest, etc., when done under rules / in approved labs, is legal.
• What is restricted is doing family relationship tests (especially for legal status) without court/A‐legal oversight, or using non-approved labs/kits in ways that would affect legal status like paternity, citizenship, etc. 



Practical Implications
• If someone in Israel wants to do a paternity test or other family relationship test for legal purposes, they must apply to a Family Court, get an order, use an accredited lab. 
• For “fun” ancestry testing (like many home kits) or curiosity, there may be obstacles: e.g. some kits are not sold in Israel or their legal recognition is limited.

If Jesus Christ took a DNA test in 2025 what might the results look like?

That’s a fascinating question. To imagine what Jesus Christ’s DNA test might look like if He were alive today and submitted a sample in 2025, we can only base it on historical, geographical, and anthropological evidence.

Here’s a breakdown of what we might expect:

1. Ethnic and Regional Origins
• Primary ancestry: Jesus was a Jew of the 1st century, born in Bethlehem and raised in Nazareth in Roman-occupied Judea (modern-day Israel/Palestine).
• This places Him genetically in the ancient Levantine population, closely related to modern Palestinians, Mizrahi Jews, Samaritans, Lebanese, Syrians, and Druze.
• Possible admixture: Given the long history of the region as a crossroads (Egypt, Mesopotamia, Greece, Rome, Arabia), He may have carried trace ancestry from surrounding areas.

2. Modern DNA Test Categories

If Jesus took something like AncestryDNA or 23andMe, His results might show clusters like:
• 60–80% Levant (Israel/Palestine/Lebanon/Syria) – reflecting His Jewish ancestry tied to the tribes of Israel.
• 10–20% Arabian Peninsula – gene flow was common across the Red Sea and Arabian Desert.
• 5–10% North African (Egyptian) – trade and migration between Judea and Egypt were frequent.
• Small traces of Southern European (Greek/Roman) – due to centuries of Hellenistic and Roman presence.

3. Haplogroups
• Y-DNA (paternal line): Tradition traces Jesus’ earthly lineage to King David (tribe of Judah). Many Levantine men today belong to haplogroups like J1 or J2, common among Jewish and Middle Eastern populations.
• mtDNA (maternal line): Mary, His mother, would have passed Him a haplogroup also rooted in the Near East, likely something like K, H, N, or J, all common in the region.

4. Appearance vs. DNA
• DNA would not say “He looked European” or “African.” Instead, it would confirm He was a Semitic man of the 1st-century Levant—dark hair, brown skin, and Middle Eastern features, matching the people of that region then and now.



✨ So, in short: if Jesus took a DNA test in 2025, His results would mostly reflect ancient Levantine Jewish ancestry, with small traces of surrounding Mediterranean, Arabian, and North African lineages, mirroring the diverse crossroads of His homeland.
