Genetics
Across
- 4. a trait that is expressed only when genotype is homozygous
- 5. Genetic code
- 6. the genetic makeup of an organism
- 7. The presence of two different alleles at a particular gene locus.
- 9. a change in the DNA sequence of an organism
- 11. the relationship between two versions of a gene
- 12. is the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
- 14. one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
- 15. the presence of two complete sets of chromosomes in an organism's cells, with each parent contributing a chromosome to each pair.
Down
- 1. a type of inheritance in which two versions (alleles) of the same gene are expressed separately to yield different traits in an individual.
- 2. A type of genetic change that involves the absence of a segment of DNA
- 3. a disease caused in whole or in part by a change in the DNA sequence away from the normal sequence.
- 8. the scientific study of genes and heredity
- 10. The physical site or location of a specific gene on a chromosome.
- 13. the presence of a single set of chromosomes in an organism's cells
