Chromosome spread of a male common wallaroo (male wallaroos , like
most mammals, have an X and a Y chromosome)
1. Arrange these chromosomes to construct a karyotype.
2. Copy your karyotype onto the next slide and follow the instructions provided.

One haploid chromosome set Second haploid chromosome set
3. These chromosomes are from a diploid cell, which means there are two sets (two of
each unique chromosome). Separate the two chromosome sets into haploid groups—
one set on the left and one set on the right. Remember, a chromosome ‘set’ consists
of one of each unique chromosome.
