3. Even differences show relatedness
Human- 46 chromosomes Chimpanzee- 48 chromosomes
Even differences show relatedness
Chimpanzees have 2 smaller chromosome pairs we don’t have
Humans have 1 larger chromosome pair (#2) they don’t have.

TELOMERES IN MIDDLE
____________________
All chromosomes have special sequences called TELOMERES at their ends to protect the strands during replication.

Human chromosome is only human chromosome that has telomere sequences at the ends BUT ALSO IN THE MIDDLE suggesting it was made by joining two other chromosomes together. → →

Chromosome #2 has a second inactive centromere region . . .
suggesting it was made by joining two other chromosomes together.

BANDING PATTERN MATCHES
________________________
If you take the two smaller chromosomes they have that we don’t, and place them end to end, the banding pattern is identical to human chromosome #2
