3. In some species, sexual ornaments may evolve to signal to females that the male will providehigh levels of paternal care. However, in other species, such as the red-crested cardinal picturedbelow, there is a negative correlation between the expression of the ornament and paternal care.a) In such species, how might we explain female preference formales with redder heads? b) Imagine that females in the population vary in body condition.How might we expect female mate preferences to vary with femalebody condition? Explain your answer. c) What effect might this have on the strength of sexual selectionfor redder heads?
1.  Mice and Genetics Research:  Imagine you are working in a genetics lab with the house mouse Mus musculus, a model organism for genetics research.  You want to determine whether a trait you have discovered in mice is dominant or recessive. Explain how you would design an experiment to answer this question. Predict what types of outcomes are possible.  Which would indicate that the trait is dominant?  Which would indicate that it is recessive? 2.  Model Genetic Organisms:  Why are mice considered a model genetic organism?  Would humans fit this description
In certain parts of Africa where malaria is prevalent there is an apparent advantage to being heterozygous for the recessive allele that causes sickle-cell anemia.  Suppose a couple, both heterozygous for this allele, plans to have four children.  What is the probability that all four will be heterozygous for the sickle-cell allele (assuming that none are from multiple births)? Explain how they can determine this using a Mendelian cross.
