The zika virus was first identified in Uganda in 1947. The virus is transmitted from person to person by a bite from a mosquito. It is commonly carried by the Aedes mosquito which is prevalent throughout Central Africa. The virus has more recently spread to the Americas (South, Central, and now North) and is expected to spread to Europe. There is a concern that the virus may reach epidemic proportions. Zika virus is related to yellow and dengue fever. Common symptoms are low grade fever and a distinctive skin rash and other symptoms include vomiting, headache, and muscle and/or joint pain. Pregnant women should avoid traveling to areas known to have zika virus present because the virus is known to cause microcephaly and developmental difficulties related to the central nervous system. Based on the paragraph above, class discussions, and other VALID (be careful with your selection of e-materials! CDC – Center for Disease Control is a good place to start) sources of information please answer the following questions.
1. State a reason why the virus has spread to the Americas and likely to spread to Europe.
2. Define the term microcephaly.
3. What bones of the fetal skull would be affected by zika? Specifically, what area of the CNS is not fully developed in microcephalic individuals.

Various cultures designate racial categories differently, and they often base these categories on very different traits. For example, some cultures use nose shape as one of the defining traits for a racial group. Other cultures do not use nose shape in defining racial groups, but use hair color instead. Conduct a survey in person on your campus, via social media accounts online, or among your friends and family. Ask at least 20 people what five traits they think are most important when distinguishing racial groups. Document the responses, and then review the data. Did every person use the same traits? What do differences in racial classification such as these suggest about the universality of race and racial groupings?

A certain species of lizard comes in three colors: cream, golden, and brown. All lizards are a single solid color (ie, none ever have spots or stripes) You carry out matings between these lizards, and collect the following data:

• Cream and brown lizards can be true-breeding, but golden lizards never breed true.
• Matings between cream and golden lizards always yield cream and golden offspring in a 1:1 ratio.
• Matings between brown and golden lizards always yields brown and golden offspring in a 1:1 ratio.
• Mating golden lizards with other golden lizards always yields brown lizards, golden lizards, and cream lizards in a ratio of 1:2:1, respectively.

Required:
Assign allele symbols to all alleles of the lizard color gene, and indicate which genotypes result in which phenotypes.
