- 2. passing on of characteristics from parents to offspring
- 7. (Genetics) any of the microscopic rod-shaped structures that appear in a cell nucleus during cell division, consisting of nucleoprotein arranged into units (genes) that are responsible for the transmission of hereditary characteristics.
- 8. Any of the alternative forms of a gene or other homologous DNA sequence
- 9. characteristic that is inherited; can be either dominant or recessive
Down
- 1. A hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and is transcribed into an RNA molecule that may function directly or be translated into an amino acid chain. Genes undergo mutation when their DNA sequences change.
- 3. a. Genetics Of, relating to, or designating an allele that does not produce a characteristic effect when present with a dominant allele.
- 4. A nucleic acid that carries the genetic information in cells and some viruses, consisting of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine.
- 5. The observable physical or biochemical characteristics of an organism, as determined by both genetic makeup and environmental influences.
- 6. Genetics Of, relating to, or being an allele that produces the same phenotypic effect in heterozygotes as in homozygotes.
- 10. A nucleic acid present in all living cells and many viruses, consisting of a long, usually single-stranded chain of alternating phosphate and ribose units, with one of the bases adenine, guanine, cytosine, or uracil bonded to each ribose molecule.
