Summary Introduction

To write:

Two animals expected to have similar chromosomal characters. An experiment to test their similarity.

Introduction:

Chromosome consists of DNA molecule that contains the genome (genetic material) of an organism. This 3-D genome structure is very important in transcription of DNA.

Explanation of Solution

Humans and animals are expected to have similar chromosomal characters. Also because the evolution theory predicts that humans have evolved from the monkeys.The number of chromosomes in humans are 46 and that ofchimpanzees are 48. The chromosomal number of chimpanzees are similar to that of potatoes (48).

The genetic difference between a human and a chimpanzee or bonobo (close trait of chimpanzee) is about $1.2\%$ . As per the 2005 research humans share about $99\%$ of DNA with chimpanzees.

Conclusion

Humans belong to the group of Primates and often are compared with apes. The similarities are found comparing the anatomy,behaviour and some DNA evidence. Chimpanzees and bonobos share many traits like human.
