GPS for our study of Genetics

• S7L3 Students will recognize how biological
  traits are passed on to successive generations.
• S7L3a Students will explain the role of genes and
  chromosomes in the process of inheriting a
  specific trait.
• S7L3c Students will recognize that selective
  breeding can produce plants and animals with
  desired traits.
