1. What is the Genetic Probability Equation?

The genetic probability equation predicts the likelihood of specific genetic outcomes in guinea pig offspring based on parental genes. It provides a mathematical foundation for understanding inheritance patterns.

2. How Does the Calculator Work?

The calculator uses the genetic probability equation:

Where:

• \( P \) — Probability of genetic outcome (dimensionless)
• \( G1 \) — Gene 1 contribution
• \( G2 \) — Gene 2 contribution
• \( T \) — Total possible genetic combinations

Explanation: The equation calculates the probability by multiplying the contributions of both genes and dividing by the total possible combinations.

3. Importance of Genetic Probability

Details: Understanding genetic probabilities helps breeders predict coat colors, patterns, and other inheritable traits in guinea pig offspring.

4. Using the Calculator

Tips: Enter the gene contributions (typically between 0-1 for probabilities) and the total possible combinations. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between genotype and phenotype probability?
A: Genotype probability predicts genetic combinations, while phenotype probability predicts visible traits which may involve multiple genes.

Q2: How accurate are these predictions?
A: Predictions are mathematically accurate for single-gene traits, but real-world outcomes may vary with polygenic traits.

Q3: Can this predict recessive traits?
A: Yes, but you need to account for both dominant and recessive allele combinations in your calculations.

Q4: What are common gene values for guinea pigs?
A: Common values are 0.25, 0.5, or 0.75 for single traits, representing different inheritance probabilities.

Q5: How does this apply to coat color genetics?
A: For simple coat colors controlled by one gene, this works directly. For complex patterns, multiple equations may be needed.
