  1. 5. The trait that expresses itself when factors for two opposing traits are present.
  2. 7. The second generation of offspring.

  4. 11. To do this, the petals must be opened and the pollen sacs removed, and then pollen can be supplied from another plant.
  5. 12. The specific genes that an organism contains (its genetic makeup).
  6. 13. The particular site on a chromosome where a particular gene is located.

  1. 1. This is when the petals are arranged in a flower so that the pollen naturally fertilizes the pistil.
  2. 2. The first generation of offspring.
  3. 3. The condition in which both alleles in a cell are different.
  4. 4. A cross between individuals that deals with only one set of alleles (one set of opposing characteristics).
  5. 6. The trait that is masked (or hidden) when two genes for opposing traits are present.
  6. 8. An alternate form of a gene that occupies the same locus on homologous chromosomes (often expressed by letters).
  7. 10. The physical expression of an organism's genes (what it looks like).
