Share the Love!!! Give a Hug, High Five, Hand Pound,

Hand Shake or all of the above to at least 3 people

Lab Report Feedback 95% of students did NOT have adequate

data support in their conclusions. (WHERE ALMOST ALL of point deductions came from!!!)

20% of students did not address ALL ideas on the checklist (#sigh).

50% of students did not adequately explain or label their figures/charts/graphs.

The Man, The Legend, The Friar!

Gregor Mendel (1822-1884)

Key ConceptsAlleles: Different VERSIONS of a gene.

(Examples: hair color, eye color)

Dominant versus recessive alleles(A and a)

Genotype versus Phenotype

Major Accomplishments

Known as the “Father of Genetics,” for his work with pea plants.

Mendel demonstrated that the inheritance of certain traits in pea plants follows particular patterns.

Demonstrated that particular phenotypes had certain genotypes behind them and with that information you could predict the traits of the offspring.

What did he do?

Overnight Fame!

How did he do it?

Another Pretty Cool Scientist.

Practical Use

Dominant-Yellow

Recessive-Green
