To determine the number that should replace the letter [tex]\( x \)[/tex] in the "Seed color" row, let's follow these steps:
1. Identify Total Plants for Seed Color:
The total number of plants considered for the seed color trait is given as 18,066.
2. Determine the Number of Yellow Seed Plants:
The number of plants with yellow seeds is provided as 6,022.
3. Calculate the Number of Green Seed Plants:
To find the number of green seed plants, we need to subtract the number of yellow seed plants from the total number of plants.
[tex]\[
\text{Number of green seed plants} = \text{Total number of plants} - \text{Number of yellow seed plants}
\][/tex]
4. Substitute the Values:
Substituting the given numbers:
[tex]\[
\text{Number of green seed plants} = 18{,}066 - 6{,}022
\][/tex]
5. Perform the Subtraction:
By performing the subtraction:
[tex]\[
18{,}066 - 6{,}022 = 12{,}044
\][/tex]
6. Conclusion:
The number that should replace the letter [tex]\( x \)[/tex] in the "Seed color" row is 12,044.
Therefore, the number that should replace [tex]\( x \)[/tex] is 12,044.
The correct answer is: 12,044.
