How does the creation of variations in a species promote survival
2. How does the creation of variations in a species promote survival?
Heredity and Evolution
if a trait A exists in 10% of a population of an asexually reproducing species
if a trait A exists in 10% of a population of an asexually reproducing species; and a trait B exists in 60% of the same population, which trait is likely to have arisen earlier?

Phenotypic ratio is easily detectable by the trait, but we can not confirm the genotypic ratio by phenotype. So to know the genotypic ratio we cross-pollinate the f2 generation with a pure recessive variety.
