genetic disorders 

  • DNA - deoxyribonucleic acid
    • DNA is made of bases (ATCG) and a backbone that holds it together
    • it also has a double helix shape
  • location
    • DNA is found in the nucleus of the cell
    • it is passed on from offspring in the gametes
    • DNA codes for all our characteristics
  • storage
    • DNA is coiled into chromosomes
    • each chromosome is a large section of DNA
    • humans have 46 chromosomes
    • the location of a gene is called locus (plural = loci)
  • monohybrid inheritance
    • single characteristic
    • 2 alleles and 1 gene
    • eg: plant height
    • tall is dominant to dwarf
    • if heterozygous tall plant is crossed with a homozygous dwarf plant,what will the phenotype of the offspring be?
    • T for tall and t for dwarf
