What is a karyotype in anthropology?
A karyotype is the number, size, and shape of chromosomes in an organism.
Why are karyotypes useful diagrams?
karyotypes allow you to study differences in chromosome shape, structure, and size. By looking at kayotypes you should be able to determine the number of autosomes and sex chromosomes present.
What does telomeres mean in biology?
A telomere is the end of a chromosome. Telomeres are made of repetitive sequences of non-coding DNA that protect the chromosome from damage. Each time a cell divides, the telomeres become shorter. Eventually, the telomeres become so short that the cell can no longer divide.

How do karyotypes match chromosomes?
In a given species, chromosomes can be identified by their number, size, centromere position, and banding pattern. In a human karyotype, autosomes or “body chromosomes” (all of the non–sex chromosomes) are generally organized in approximate order of size from largest (chromosome 1) to smallest (chromosome 22).
What are 3 things that can be determined from a karyotype?
