If gene frequency for PTC nontaster is 0.4, then what will be the number of heterozygotes tasters in a population?

To determine the number of heterozygote tasters in a population, you will need to know the size of the population. Assuming you have the population size, you can follow these steps to calculate the number of heterozygotes tasters:
Step 1: Calculate the frequency of PTC tasters.
The allele frequency for PTC nontasters is given as 0.4. Assuming a diploid organism, the PTC taster allele frequency would be 1 - 0.4 = 0.6.
Step 2: Calculate the frequency of heterozygotes.
The frequency of heterozygotes can be calculated using the equation 2 * p * q, where p represents the frequency of one allele (PTC nontaster) and q represents the frequency of the other allele (PTC taster). In this case, p = 0.4 and q = 0.6.
Substituting the values, we get: 2 * 0.4 * 0.6 = 0.48.
Step 3: Calculate the number of heterozygotes tasters.
To calculate the number of heterozygotes tasters, you will need the total population size. Let's assume the total population size is N.
Multiply the frequency of heterozygotes calculated in step 2 (0.48) by the population size (N):
Number of heterozygote tasters = 0.48 * N.
Now that you have the formula, you can plug in the specific population size value to calculate the number of heterozygote tasters.
