The egg and sperm cells produced by pandas have 21 chromosomes. This means that the parent (germ) cells from which panda gametes originate have ___________ chromosomes. 

A population of salamanders live along the edge of a north-south mountain range. The populations from the east and west slope eventually join in a low northern pass and interbreed, producing fertile offspring, but they do not circle around the southern edge because of a desert barrier. When glaciers move southward, the populations are pushed south of the northern pass and are isolated. While isolated, the two populations develop enough differences over time that when the glaciers retreat north and the salamanders again share the same pass, they no longer mate at the same time, nor can they produce fertile offspring. These salamanders have experienced

The domesticated honey bee found in the United States (Apis mellifera)—originally from Europe—is slow to sting and stores large amounts of honey, but does not tolerate subtropical conditions (found in areas about 35 degrees north and south of the equator) as well as the “Africanized” honey bee (Apis mellifera scutellata). Because the European honey bee was performing poorly as a honey producer in South America, biologist Warwick Kerr imported the African subspecies to Brazil in the 1950s. He began a breeding experiment to attempt to produce a honeybee more tolerant of the subtropical concitions found in South America. The African honey bee was more tolerant of the environmental conditions, but produced less honey stores and was quite aggressive. In 1957, a mistake by a lab technician resulting in the escape of ~26 African queens. As a result, these African honeybee queens interbred with wild European honeybee populations, forming hybridized bees that we now call “Africanized bees.” The African genotype spread north among European honeybee populations at a rate of about 300 kilometers each year; in 1985 the first Africanized honeybees were discovered in the United States in California. Unexpectedly, European and hybrid hives died out in subtropical areas and the remaining honeybee populations were essentially 100 percent Africanized. In the United States Africanized honeybees are common in the south and southwestern states. How would this be explained in evolutionary genetics terms?

Researchers have long debated different hypotheses for the phylogeny and classification of species in the bear family, Ursidae. In 2008, researchers obtained complete mitochondrial DNA (mtDNA) genome sequences for the eight living species of bears. Based on these data, the researchers constructed a phylogenetic tree for the family Ursidae. Based on the phylogeny, who is the closest relative of the American black bear?

In humans, the allele for a widow’s peak (W) is dominant over the allele for a straight hairline (w). What would be the expected phenotypic ratio of the offspring of two individuals who are heterozygous for this gene?

In some species of oysters found in shallow, rocky waters, both light and dark-colored shells are common, whereas intermediate-colored oysters are rare. This is likely because lighter oysters are similar in color to the rocks, while dark oysters blend into the shadows cast by the rocks. Intermediate-colored oysters are heavily preyed upon by crabs and other predators due to being more conspicuous. Selection for these two extreme phenotypes is an example of
