Describe the chromosome, gene, and alleles. What is the difference between a characteristic and a trait? List the characteristics and traits that are listed in your textbook and analyzed by Gregor Mendel. List dominant and recessive traits for each characteristic. How is a gene different from an allele? Draw a pair of homologous chromosomes with heterozygous alleles, a pair of homologous chromosomes with homozygous dominant alleles, and another pair of homologous chromosomes with homozygous recessive alleles. Pick your own letters for the genes. Define a locus. How are genes, proteins, and traits related to each other? What are gametes? During meiosis, what happens to the pairs of alleles? 

Directions: For each option, complete the Punnett Squares; list possible gametes of the parents; and list all possible genotypes and phenotypes of the potential offspring. Brown eye color is dominant over blue eye color. A heterozygous female marries a homozygous dominant man. What are the eye color possibilities if they choose to have children? (select the letters "B" and "b" for your alleles) The straight thumb is recessive, and the hitchhiker's thumb is dominant. If a woman with a straight thumb marries a man who is homozygous dominant for hitchhiker's thumb, predict the outcomes
