Module 5 obj. 20-21

• Mitosis creates two daughter cells that are identical to the "parent"
• Meiosis halves the DNA content in Meiosis I and the MeiosisII resembles mitosis

• Somatic cells make up the majority of the body's cells
• -use mitosis to divide 
• -these are diploid (2n)
• -Two copies of each numbered chromosome plus to sex chromosomes (XX or XY)
• Germa Cells (gametes) are the reproductive cells 
• -use meiosis to divide
• -sperm and egg
• these cells are haploid (n)
• -when they join they make a diploid embryo

Because the mother's and fathers gamets each contain one copy of each gene, child inherits one copy of a gene from mother and one from father
