Homologous Chromosomes	Level 1 None of the chromosomes are paired with their homolog.	Level 2 Some of the chromsomes are paired with their homolog.	Level 3 Majority of the chromsomes are paired with their homolog.	Level 4 All chromosomes are paired with their homolog.
# of Homologous Groups	Level 1 None of the twenty three groups of chromosomes exist and none of the autosomal pairs are numbered.	Level 2 Some of the twenty three groups of chromosomes exist and some of the autosomal pairs are numbered.	Level 3 Majority of the twenty three groups of chromosomes exist and majority of the autosomal pairs are numbered.	Level 4 All twenty three groups of chromosomes exist and all autosomal pairs are numbered.
Chromosome Arrangement	Level 1 None of the chromosomes are arranged from largest to smallest. Sex chromosomes are missing.
