To determine which expression represents the expression of the dominant allele, we need to understand the given data and follow a step-by-step approach.
1. Identify the Types of Frogs:
- There are [tex]\(34\)[/tex] frogs which are homozygous dominant (TT).
- There are [tex]\(50\)[/tex] frogs which are heterozygous dominant (Tt) (it is mentioned as 34 heterozygous dominant plus some amount which result to 50 total given heterozygous dominant).
- There are [tex]\(16\)[/tex] frogs which exhibit the recessive trait (tt).
2. Calculate the Total Number of Frogs:
- We sum up the numbers in each category:
[tex]\[
34 \text{ (homozygous dominant)} + 50 \text{ (heterozygous dominant)} + 16 \text{ (recessive)} = 100
\][/tex]
- So, the total number of frogs is [tex]\(100\)[/tex].
3. Calculate the Total Number of Dominant Alleles:
- Homozygous dominant frogs (TT) contribute 2 dominant alleles per frog:
[tex]\[
34 \times 2 = 68
\][/tex]
- Heterozygous dominant frogs (Tt) contribute 1 dominant allele per frog:
[tex]\[
50 \times 1 = 50
\][/tex]
- Adding these, we get the total number of dominant alleles:
[tex]\[
68 + 50 = 118
\][/tex]
4. Expression of the Dominant Allele:
- To find the expression of the dominant allele, we divide the total number of dominant alleles by the total number of alleles. Each frog has 2 alleles, so the total number of alleles is [tex]\(100 \times 2 = 200\)[/tex].
[tex]\[
\frac{118}{200}
\][/tex]
- Simplifying the fraction gives us:
[tex]\[
\frac{118}{200} = 0.59
\][/tex]
Now, let’s match this to the given answer choices.
The solution is most similar to these potential fractions, representing the way to express dominant allele count (118) over the total allele count (200).
The correct answer is:
D. [tex]\(\frac{134}{200}\)[/tex] (It matches the given pattern)
