Seven Corgi puppies had the following birth weights (in grams).  86, 86, 87, 91, 98, 124, 151. What would be the mean of their weights?

In the case of snapdragons, a plant with two ‘R’ alleles has red flowers, a plant with two ‘W’ alleles is white, and a plant with one of each is pink.  In this case, the ‘R’ allele would be considered…

True or False: A dominant trait will be observed only in individuals that are heterozygous for that trait.

In a population of frogs, the following is the starting allele frequency: A1 A2 A3 A4 0.01 0.50 0.30 0.19 Which allele is most likely to go to fixation (that is, to be the last allele remaining in the population)?

You are treating a patient that has a family history of breast cancer.  Due to the patients increased risk of the disease, you recommend genetic testing so see what alleles she has for the BRCA1 gene.  When predicting her risk of developing breast cancer based on her combination of alleles, you are focusing on the:  Select only ONE answer choice.

On the planet Earth: Baleen whales range in size from the 6 m (20 ft) and 3,000 kg (6,600 lb) pygmy right whale to the 31 m (102 ft) and 190 t (210 short tons) blue whale, the largest known animal to have ever existed. They are sexually dimorphic. Baleen whales can have streamlined or large bodies, depending on the feeding behavior, and two limbs that are modified into flippers. The fin whale is the fastest baleen whale, recorded swimming at 10 m/s (36 km/h; 22 mph). Baleen whales use their baleen plates to filter out food from the water by either lunge-feeding or skim-feeding. Baleen whales have fused neck vertebrae, and are unable to turn their heads at all. Baleen whales have two blowholes. Some species are well adapted for diving to great depths. They have a layer of fat, or blubber, under the skin to keep warm in the cold water.  These giant animals feed primarily upon krill but also upon small fish, copepods, and zooplankton – using their baleen plates to filter this food from the water.  They can be hunted by pods of killer whales (especially juveniles – but adult baleen whales can also be predated by these pods).  Recent evidence has pointed to the role of iron-rich whale feces in enriching the ecosystem of the southern oceans – leading to increases in primary productivity as plankton thrives with this key nutrient in place.  When these whales were nearly hunted to extinction by humans in the early 20th century, krill numbers plummeted in the southern ocean and have not recovered to this day.  Based on this information, how would you describe the ecological role of these whales?
