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
