genetic diagrams

Cards (11)

  • what is an allele
    different version of all genes
  • what does homozygous mean 

    if 2 versions of a gene on a pair of chromosomes are the same(GG, gg)
  • what does heterozygous mean 

    if 2 versions of a gene on a pair of chromosomes are different (Gg)
  • how are the characteristics determined if the two alleles are different(Gg)

    the dominant allele(G)is the characteristics that are shown
  • what is the non dominant allele called 

    recessive(in Gg, recessive would be g)
  • what must the alleles be for an organism to show its recessive characteristics 

    two of the same recessive allele(gg)
  • how do you show a dominant allele
    upper case letter(G)
  • how do you show a recessive allele
    lower case letter(g)
  • what is a genotype
    combinations of alleles you have (GG,Gg,gg)
  • what is a phenotype
    effect that alleles have on organism characteristics(e.g. black or brown hair)
  • example of genetic diagrams for alleles and offspring’s
