1. What is the Vahaduo DNA Calculator?

The Vahaduo DNA Calculator estimates genetic probability from centimorgans (CM) and total shared DNA. It provides a simple way to calculate the probability of a genetic relationship based on shared DNA segments.

2. How Does the Calculator Work?

The calculator uses the DNA probability equation:

Where:

• \( P \) — Probability (dimensionless)
• \( CM \) — Centimorgans (measure of genetic linkage)
• \( T \) — Total shared DNA

Explanation: The equation calculates the probability of a genetic relationship by comparing the shared centimorgans to the total DNA.

3. Importance of DNA Probability Calculation

Details: Accurate DNA probability estimation is crucial for genetic genealogy, determining familial relationships, and understanding inheritance patterns.

4. Using the Calculator

Tips: Enter centimorgans (CM) and total shared DNA (T). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are centimorgans?
A: Centimorgans (cM) are units of genetic linkage that represent the likelihood of recombination between two markers.

Q2: What is a typical CM value for close relatives?
A: Parent-child relationships typically share about 3400 cM, while siblings share about 2600 cM.

Q3: How accurate is this calculation?
A: The calculation provides a basic probability estimate but doesn't account for all genetic factors or mutations.

Q4: Can this be used for paternity testing?
A: While it can suggest probabilities, professional paternity tests use more comprehensive methods.

Q5: What's considered a high probability?
A: Values closer to 1 indicate higher probabilities of a genetic relationship.
