Biologists once assumed that the phenotype of a dominant allele would always be the most common phenotype in a population. Which finding led biologists to a different conclusion?
In 1998, paleoanthropologist Rick Potts published an article in The Yearbook of Physical Anthropology, a peer-reviewed journal. The article was titled “Environmental Hypotheses of Hominin Evolution.” In his paper, Potts claimed that great variations in environmental conditions over time were responsible for the adaptability of humans and the success of our species. Which would most likely be found in his paper?

Why might this not be the best article to reference?
In four o’clock plants, there are three phenotypes for flower color but only two alleles. In one population, q2 = 0.169, and the population is assumed to be in Hardy-Weinberg equilibrium. The table below shows the number of plants of each phenotype that are expected in a population of 1,000 plants in the next generation.PhenotypeNumber expectedRed flowers105Pink flowers484White flowers411In the next generation, what p value is expected?
The frequency of alleles in a population that is in Hardy-Weinberg equilibrium
Which feature separates humans from other primates?
In pea plants, purple flower color, C, is dominant to white flower color, c. The table shows the frequencies of the dominant and recessive alleles in three generations of peas in a garden.Allele Frequency for Flower Color in PeasGenerationpq10.600.4020.640.3630.750.2540.800.20Which generation showed the greatest frequency of having one of each allele?
