copy deck
- A segment of DNA that transmits information from parent to offspring
- Gene
- The two copies of each chromosome are called
- homologous
- The two chromatids are attatched by a protein disk at a point called
- centromere
- When a cell contains two homologues of each chromosome it is called
- diploid
- Sometimes the fragment reattaches to the original chromosome in the reverse orientation, producing a mutation called a
- inversion
- The fragment may join a nonhomologous chromosome, in an event called
- translocation
- Chromosomes that differ between males and females are called
- sex chromosomes
- egg cells and sperm cells are called
- gametes
- A cell that contains only one homologue of each chromosome
- haploid
- A fertilized egg cell is called a
- zygote
- THe condition in which a diploid cell has an extra chromosome is called a
- trisomy
- The collection of chromosomes found in an individual's cells.
- karyotype
- Changes in an organism's genetic material
- mutations
- When a fragment of a chromosome breaks off, it can be lost when the cell divides causing a mutation called
- deletion
