Genetics

3. A cell containing two sets of chromosomes, one inherited from each parent, typically denoted as \(2n\).
4. A permanent, random change in the DNA sequence.
6. A cell containing only one set of chromosomes (e.g., sperm or egg cells), typically denoted as \(n\).
9. Thread-like structures in the nucleus that contain DNA.
12. The observable, physical characteristics of an organism
13. Having two different alleles for a particular gene
14. gene variant that masks the presence of another allele and is expressed in the phenotype, even if only one copy is present.
15. One of two or more alternative forms of a gene at a specific location, inherited from each parent.

1. studies how living things inherit traits—such as hair color, height, or risks for diseases—from their parents
2. Having two identical alleles for a particular gene
5. The process of copying a segment of DNA into RNA
7. The process by which genetic information is passed from parent to child.
8. A sequence of three DNA or RNA nucleotides that corresponds to a specific amino acid during protein synthesis
10. The passing on of physical or mental characteristics (genes) from parents to offspring.
11. A gene variant that is only expressed in the phenotype when two copies are present.
