Heterozygous Frequency Formula

The following two example problems outline the steps and information needed to calculate the Heterozygous Frequency.

HF = 2*q*p

Variables:

• HF is the Heterozygous Frequency ( )
• q is the recessive q value 
• p is the dominant p value 

To calculate the heterozygous frequency, multiply 2 times the recessive q value and the dominant p-value.

How to Calculate Heterozygous Frequency?

The following steps outline how to calculate the Heterozygous Frequency.

1. First, determine the recessive q value. 
2. Next, determine the dominant p value. 
3. Next, gather the formula from above = HF = 2*q*p.
4. Finally, calculate the Heterozygous Frequency.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

recessive q value = .2

dominant p value = .8

HF = 2*q*p = ?
