Chapter 6 Meiosis


Chapter 6



Section1: Chromosomes & Meiosis




Your body produces 2 types of cells....

1. Germ Cells aka Sex Cells aka Gametes



2. Somatic Cells aka body cells (all other cells in your body)



The number of chromosomes varies within species....

Humans have 23 pairs of chromosomes in each cell (46 chromosomes total)

Fruit flies have 4 pairs of chromosomes in each cell (8 chromosomes total)
Dogs have 39 pairs in each cell
Cats have 19 pairs...


No matter what species you have each chromosome has its pair (the same size and copies of the same genes)

These two pairs of chromosomes are called HOMOLOGOUS CHROMOSOMES



The EXCEPTIONS are the Sex Chromosomes... 

Fertilization happens when an egg (having 23 chromosomes) combines with the sperm (having 23 chromosomes) forming a DIPLOID CELL



Haploid Vs Diploid




Syndromes of Sex Linked Chromosomes

Turner Syndrome




Klinefelter Syndrome
              Can Species Interbreed?


Mitosis vs Meiosis




What is Meiosis?
