Title: Can you determine which allele is dominant and which is recessive from their frequencies?
Post by: buffyl13 on Feb 11, 2013
Or is it impossible. Are there too many other variables?

Ex: Q7. A frog population has two alleles for skin color at the following relative frequencies: Allele SC1 = 0.8, Allele SC2 = 0.2. Allele SC2 is:

Dominant
Recessive
Co-dominant
Impossible to determine dominance from the information given.

Impossible to determine dominance from the information given since it tells us nothing about the phenotype of the skin color.
