In pea plants, purple is dominant to white. A cross was made between a heterozygous plant with purple flowers and a homozygous plant with white flowers. What is the expected phenotypic ratio of the offspring?

In a series of field experiments, David Tilman and colleagues investigated biodiversity and ecosystem function. They found a relationship between

The cladogram below shows the evolutionary relationships (left to right) of lancelet, lamprey, salmon, lizard, and rabbit. Which of the following is a shared derived character of the salmon, lizard, and rabbit?

GGG and GGC are codons for the amino acid, glycine. A mutation caused the insertion of a cytosine in place of the third guanine during DNA replication. Over many generations the DNA changes so that the frequency of GGC is similar to that of GGG. What effect does this mutation have on the population’s mean fitness?

Evolution, viewed on a small scale, as it relates to changes in a single gene or allele frequency in a population over time, is called __________.
