pedigree analysis
T_3255
FIGURE 1.1 In a pedigree, squares symbolize males, and circles represent females. A horizon- tal line joining a male and female indicates that the couple had offspring. Vertical lines indicate offspring which are listed left to right, in order of birth. Shading of the circle or square indicates an individual who has the trait being traced. In this pedigree, the inheritance of the recessive trait is being traced. A is the dominant allele, and a is the recessive allele.

polygenic traits
T_3277
FIGURE 1.1 Polygenic traits tend to result in a distribu- tion that resembles a bell-shaped curve, with few at the extremes and most in the middle. There may be 4 or 6 or more alleles involved in the phenotype. At the left extreme, individuals are com- pletely dominant for all alleles, and at the right extreme, individuals are completely recessive for all alleles. Individuals in the middle have various combinations of recessive and dominant alleles.

population growth patterns
T_3281
FIGURE 1.3 Usually, populations first grow exponentially while resources are abundant. But as populations increase and re- sources become less available, rates of growth slow down and slowly level off, reaching the carrying capacity. The carrying capacity is the upper limit to the population size that the environment can support. This type of growth is shown as an "S-shaped" curve below ( Figure 1.3) and is called logistic growth. Why do you think occurs?

FIGURE 1.1 This picture shows the proper way to wash your hands. Frequent hand washing helps prevent the spread of pathogens. and wash your hands often to avoid spreading pathogens to other people. Dont go to work or school if youre vomiting, have diarrhea or are running a fever (and if you are, drink plenty of fluids). Also, to avoid infectious diseases, dont share personal items; use your own toothbrush, comb, and razor. And avoid sharing drinking glasses or dining utensils.

Ge- ologic time is the same as the age of the Earth: between 4.404 and 4.57 billion years. Look closely for such events as the extinction of dinosaurs and many marine animals.

FIGURE 1.3 This chart shows the genetic code used by all organisms. For example, an RNA codon reading GUU would encode for a valine (Val) according to this chart. Start at the center for the first base of the three base codon, and work your way out. Notice that more than one codon may encode for a single amino acid. For example, glycine (Gly) is encoded by a GGG, GGA, GGC, and GGU. Notice there are 64 codons. Of the 64 codons, three are stop codons.
