Presentation Transcript
Slide1Heterozygous vs Homozygous
Slide2Heterozygous vs Homozygous• Pairs of alleles can be either heterozygous or Homozygous. • An allele are a pair of genes (section of DNA).
Slide3Heterozygous• Heterozygous means that there are two different alleles, one being dominate and the other is recessive. • This is represented by letters • For example: Rr, Gg, Tt • The capital means dominate gene, while the lower case means recessive.
Slide4Homozygous• Means that both alleles are exactly the same. • For example: FF, GG, TT
Slide5Dominate and recessive• A dominate allele will always be expressed over a recessive allele. • For Example: Brown eyes are dominant to blue eyes, thus brown eyes are given the letter B, as blue eyes are given the letter b. If a person has the alleles Bb, they will have brown eyes, BB they will have brown eyes, bb they will have blue eyes.
