To determine the frequency of the golden phenotype in the hamster population, follow these steps:
1. Identify the number of hamsters for each genotype and phenotype:
- Genotype GG (Golden phenotype): 12 hamsters
- Genotype Gg (Golden phenotype): 25 hamsters
- Genotype gg (Black phenotype): 13 hamsters
2. Calculate the total number of hamsters:
- Total number of hamsters = Number of GG hamsters + Number of Gg hamsters + Number of gg hamsters
- Total number of hamsters = 12 + 25 + 13
- Total number of hamsters = 50
3. Calculate the total number of hamsters exhibiting the golden phenotype:
- Total number of golden phenotype hamsters = Number of GG hamsters + Number of Gg hamsters
- Total number of golden phenotype hamsters = 12 + 25
- Total number of golden phenotype hamsters = 37
4. Find the frequency of the golden phenotype:
- Frequency is the ratio of golden phenotype hamsters to the total number of hamsters.
- Frequency of golden phenotype = Number of golden phenotype hamsters / Total number of hamsters
- Frequency of golden phenotype = 37 / 50
After these calculations, we find that the frequency of the golden phenotype in the hamster population is [tex]\( \frac{37}{50} \)[/tex].
Thus, the correct answer is:
A. [tex]\(\frac{37}{50}\)[/tex]
