  1. 5. The number, size, and shape of chromosomes in an organism's cell, usually presented as a visual arrangement of chromosomes.
  2. 9. Process of cell division that results in two daughter cells, each with the same number of chromosomes as the parent cell, used for growth and repair.
  3. 10. A type of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes found in the parent cell, necessary for sexual reproduction.
  4. 12. The passing of genetic information (traits) from parents to offspring through the transmission of genes.

  1. 1. Structures composed of DNA and proteins found in the nucleus of cells. They carry genetic information in the form of genes. These structures are the way DNA organizes itself.
  2. 2. The genetic makeup of an organism, consisting of the specific combination of alleles present for a particular set of genes.
  3. 3. Alternative forms of a gene, differing in DNA sequence, which can lead to different traits.
  4. 4. It is the molecule carrying genetic instructions for the development, functioning, growth, and reproduction of all known organisms.
  5. 6. Observable characteristics of an organism, determined by genetic and environmental factors.
  6. 7. One of the two identical halves of a replicated chromosome, joined at the centromere, which separates during cell division.
  7. 8. The observable characteristics or traits of an organism, resulting from the interaction between its genotype and the environment.
  8. 11. Units of heredity composed of DNA that encode specific traits or functions. They are the fundamental units of inheritance.
