Enter the frequencies of dominant and recessive alleles into the calculator to determine the phenotype probabilities.
Phenotype Calculation Formula
The following formula is used to calculate the phenotype probability from allele frequencies.
Phenotype Probability = (Dominant Allele Frequency / 100) * (Recessive Allele Frequency / 100) * 100
Variables:
- Phenotype Probability is the likelihood of a specific phenotype (%)
- Dominant Allele Frequency is the percentage of the dominant allele in the population (%)
- Recessive Allele Frequency is the percentage of the recessive allele in the population (%)
To calculate the phenotype probability, multiply the frequencies of the dominant and recessive alleles and then convert the result into a percentage.
What is Phenotype Calculation?
Phenotype calculation refers to the process of determining the likelihood of a specific phenotype appearing in an organism based on the frequencies of alleles in the population. This involves understanding the genetic makeup and how different alleles combine to express particular traits. Proper phenotype calculation helps in predicting genetic outcomes and understanding genetic diversity.
How to Calculate Phenotype Probability?
The following steps outline how to calculate the phenotype probability using the given formula.
- First, determine the frequencies of the dominant and recessive alleles in the population.
- Next, convert these frequencies into percentages if they are not already.
- Use the formula from above: Phenotype Probability = (Dominant Allele Frequency / 100) * (Recessive Allele Frequency / 100) * 100.
- Finally, calculate the phenotype probability by plugging in the values.
- After inserting the variables and calculating the result, check your answer with the calculator above.
