Based on a sample of Swedes, what is the allele frequency of the 'w' allele in the earwax gene?

The allele frequency indicates how common an allele is within a population. In this case, the 'w' allele represents a specific variant in the gene associated with earwax type among a sample of Swedes. If the provided answer states that the frequency is 0.1, it suggests that 10% of the alleles in this population are of the 'w' type.

To arrive at the frequency estimation, researchers typically conduct genetic surveys and analyze data from multiple individuals, identifying the proportions of various alleles. A frequency of 0.1 could imply that the 'w' allele is present in a reasonably balanced manner relative to other alleles that may be found in the earwax gene, indicating diversity within the genetic makeup of this population.

This selection makes sense within the context of genetic variation, as it suggests that the 'w' allele is neither extremely rare nor predominant, but rather part of a stable genetic distribution. Understanding allele frequencies is crucial for studying population genetics, evolutionary dynamics, and even traits related to environmental adaptations.
