Haploid vs. Diploid
1.
Name: _______________________
Haploid cells have 1 of each type of chromosome, which means they have 1 set(s) of chromosomes.
This is a combination of the maternal and paternal DNA. Gametes are the only haploid cells, and they
are formed by the process of meiosis.
2. Diploid cells have 2 of each type of chromosome, which means they have 2 set(s) of chromosomes.
This means they receive 1 set from the mother and 1 set from the father. Somatic cells are diploid,
and they are formed by the process of mitosis/cytokinesis.
Identify each cell as either haploid or diploid.

7. A somatic cell has 30 total chromosomes, which means it has 15 different types. A gamete would have 15
total chromosomes and 15 different types. The n number is 15, while the 2n number is 30.
8. A haploid cell has 20 total chromosomes, which means it has 20 different types. A diploid would have 40
total chromosomes and 20 different types. The n number is 20 while the 2n number is 40.
9. A somatic cell has 38 total chromosomes, which means it has 19 different types. A haploid would have 19
total chromosomes and 19 different types. A diploid would have 38 total chromosomes and 19 different types.
The n number is 19, while the 2n number is 38.
10. A gamete has 56 total chromosomes, which means it has 56 different types. A haploid would have 56
total chromosomes and 56 different types. A diploid would have 112 total chromosomes and 56 different
types. The n number is 56, while the 2n number is 112.
For each of the following tables, write in the number that matches the cell type.

In the space below, draw the cell described. Use two different colors, representing different parents.
Box A: a diploid cell with 2 pairs of homologous chromosomes, after crossing over.
Box B: a haploid cell with 4 chromosomes, after crossing over.
Box C: a diploid cell at the beginning of interphase, with 3 different types of chromosomes.

** For Boxes A and B, all your chromosomes should be a combination of your two colors. In Box C, each
chromosome in a pair should be a different color.
