Karyotypes
Somatic Cells
- 46 cells (diploid)
- 23 cells from dad (1st set)
- 23 cells from mom (2nd set)
\ Karyotype - A picture of all chromosomes in an individual’s cells
\ Preparation
- Take blood sample → spin it at high speed
- White and red blood cells will isolate.
- Stain them and put them underneath equipment.
\ Homologous Chromosomes
- Same Size
- Same Shape
\ Alleles - Different versions of genes
The 23rd pair of homologs are the sex chromosomes
Females: XX
Males: XY
Homologs 1-22 are autosomes
