To determine the phenotypic ratio of the offspring given the distribution, we need to count how many times each phenotype appears. We'll list the phenotypes and their occurrences and then express these counts as a ratio.
Given the phenotypic counts:
[tex]\[ 1, 1, 1, 1, 2, 2, 2, 2, 4 \][/tex]
We will count the occurrences of each unique value:
- The phenotype 1 appears 4 times.
- The phenotype 2 appears 4 times.
- The phenotype 4 appears 1 time.
Now, we will express these counts as a ratio. The counts are:
[tex]\[ 4, 4, 1 \][/tex]
Hence, the phenotypic ratio of the offspring is:
[tex]\[ 4:4:1 \][/tex]
