Traits: Traits = different physical characteristics
Heredity Heredity = the passing of traits from parent to offspring Genetics = the study of heredity =
Mendel guy sure loved his peas… Easy to study a lot of offspring looked at 7 traits
Give me an ALLELE! Genes = the factors that control traits Allele = different forms of a gene MALEFEMALE OFFSPRING
Part 1: Practice Problems Have your book open to page 83 Figure 3!!! Are the following alleles DOMINANT or recessive 1. Round seedDOMINANT! 2. Wrinkled seedrecessive… 3. Green seed DOMINANT! 4. Tall plantDOMINANT! 5. Short plantrecessive…
Part 2: Labeling alleles Scientists LOVE to use abbreviations!!! They will represent the allele with a letter. Uppercase for DOMINANT and lowercase for recessive. Example: Round seed = R and wrinkled seed = r ** always create a key and make sure to use letters that look different as lowercase
Key to alleles: TraitAllele Round seedR Wrinkled seedr Yellow seedY Green seed y TallT Shortt
Part 3:What will it look like? DOMINANT + DOMINANT =DOMINANT DOMINANT + recessive = DOMINANT recessive + DOMINANT = DOMINANT recessive + recessive = recessive
Try it now! Allel es What will it look like? 1.RR 2.Rr 3.rr 4.Yy 5.YY 6.yy 7.Tt 8.tt TraitAllele Round seedR Wrinkled seed r Yellow seedY Green seed y TallT Shortt
Part 4: Super Challenge! TraitAllele Round seedR Wrinkled seed r Yellow seedY Green seed y TallT Shortt 9. Rr Tt 10. rr YY Tt
