Mendel’s Work
What physical traits do you have that are most like your mom?
What physical traits do you have that are most like your dad?
Do parent traits always look exactly the same in the offspring?Explain your answer

Mendel’s Work
- plant/animal that always produces offspring w/same trait as parent- plant/animal that always produces offspring w/same trait as parent
- trait that always shows up in offspring when present in one parent.- trait that always shows up in offspring when present in one parent.
- trait that is always covered if a dominant allele is present- trait that is always covered if a dominant allele is present
Example: Purebred short plants always produce short plants (tt)
Example: 2 tall plants = tall offspring because tall is dominant
discoveries
dominant alleles
Recessive alleles Example: 1 tall plant + 1 short plant = tall
plant because tall is dominant

Mendel’s Work
Summary:
- different forms of a gene
- factors that control traits
- offspring with 2 different alleles for a trait
controls inheretance
symbols
alleles
gene
hybrid
Dominant alleles use capital letters.Example: TT or Tt
Recessive alleles use lower case letters.Example: Tt or tt
What letters are used? depends on the trait
Example: T = height, B = blacktraits - physical characteristics
heredity - passing traits from parents to offspring
