Across
- 5. The number, size, and shape of chromosomes in an organism's cell, usually presented as a visual arrangement of chromosomes.
- 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.
- 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.
- 12. The passing of genetic information (traits) from parents to offspring through the transmission of genes.
Down
- 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. The genetic makeup of an organism, consisting of the specific combination of alleles present for a particular set of genes.
- 3. Alternative forms of a gene, differing in DNA sequence, which can lead to different traits.
- 4. It is the molecule carrying genetic instructions for the development, functioning, growth, and reproduction of all known organisms.
- 6. Observable characteristics of an organism, determined by genetic and environmental factors.
- 7. One of the two identical halves of a replicated chromosome, joined at the centromere, which separates during cell division.
- 8. The observable characteristics or traits of an organism, resulting from the interaction between its genotype and the environment.
- 11. Units of heredity composed of DNA that encode specific traits or functions. They are the fundamental units of inheritance.
