Diploid & Haploid Cells n = the number of types of chromosomes a cell has Diploid: Definition • • • 2n -means there are two of each type of chromosome (2 sets) In this cell, n = 2, so 2x2 = 4 chromosomes for a diploid cell In humans, n=23, so 2x23=46 chromosomes for a diploid cell Picture 1 • • Use any color for blue, any color for purple (just be consistent!) 2n – Diploid Homologous Chromosomes • • A pair of (set of 2) chromosomes of the same type (size) Label the homologous chromosomes in picture 1 Somatic Cells • Name for a diploid body cell Picture 2 • • • Use the same colors as you did in picture 1 Label the homologous chromosomes Still DIPLOID Haploid • • • n – means there is only one set of each type of chromosome. In this cell, n = 2, so a haploid cell has 2 chromosomes In humans, n = 23, so a haploid cell has 23 chromosomes Gamete Name for a haploid sex cell (sperm OR egg) Picture 3 Use the same color scheme as the other pictures Under the picture, label the cell: n – Haploid
