To determine the frequency of the $ t $ allele in the population, let's break down the problem step-by-step:

1. Identifying the Total Number of Individuals:

- There are 26 individuals with the $ TT $ genotype.
- There are 64 individuals with the $ Tt $ genotype.
- There are 20 individuals with the $ tt $ genotype.

2. Calculating the Number of Alleles:

Each individual has two alleles. Thus, for the entire population, the total number of alleles is given by:
[tex]\[ 2 \times \text{total number of individuals} \][/tex]
In this case, since total number of individuals = $ 26 + 64 + 20 = 110 $,
[tex]\[ \text{Total number of alleles} = 2 \times 110 = 220 \][/tex]

3. Counting the Alleles:

- Each $ TT $ individual has 2 $ T $ alleles. Therefore, the total number of $ T $ alleles contributed by $ TT $ individuals is:
[tex]\[ 2 \times 26 = 52 \][/tex]

- Each $ Tt $ individual has 1 $ T $ allele and 1 $ t $ allele. Therefore, the total number of $ T $ alleles contributed by $ Tt $ individuals is:
[tex]\[ 64 \][/tex]

Combining the $ T $ alleles from $ TT $ and $ Tt $ individuals:
[tex]\[ \text{Total number of } T \text{ alleles} = 52 + 64 = 116 \][/tex]

- Each $ t t $ individual has 2 $ t $ alleles. Therefore, the total number of $ t $ alleles contributed by $ t t $ individuals is:
[tex]\[ 2 \times 20 = 40 \][/tex]

- Each $ Tt $ individual also contributes 1 $ t $ allele. So, the total number of $ t $ alleles from $ Tt $ individuals is:
[tex]\[ 64 \][/tex]

Combining the $ t $ alleles from $ tt $ and $ Tt $ individuals:
[tex]\[ \text{Total number of } t \text{ alleles} = 40 + 64 = 104 \][/tex]

4. Calculating the Frequency of the $ t $ Allele:

The frequency of the $ t $ allele is the number of $ t $ alleles divided by the total number of alleles:
[tex]\[ \text{Frequency of } t = \frac{\text{Total }t \text{ alleles}}{\text{Total number of alleles}} = \frac{104}{220} \approx 0.4727 \][/tex]

Thus, the frequency of the [tex]$ t $[/tex] allele in the population is approximately [tex]$ 0.47 $[/tex].
