overview
Mendel studied genetics by working in a garden that had ___ _____ .
Pea plants

10. overview
He studied their ___________ . He observed the _______ he could see and the ones he could not see.
traits

11. Look at your vocabulary!
Discussion question
What is a trait?
Look at your vocabulary!
A specific characteristic

12. Discussion answer Eye color Hair color Tall vs. Short
Trait: a specific characteristic that can change from one individual to another
Examples:
Eye color
Hair color
Tall vs. Short

13. Passing on traits
Mendel had 7 true-breeding pea plants. These types of plants produce offspring that are identical to the parents.

14. How come the offspring of the plants were identical to the parents?
discussion question
How come the offspring of the plants were identical to the parents?

15. The DNA from the parent plant was passed down to the offspring.
discussion answer
The DNA from the parent plant was passed down to the offspring.

16. During ______ , sex cells are created.
Passing on traits
meiosis
During ______ , sex cells are created.

17. Passing on traits
Sperm/egg
The male gamete is known as _____. The female gamete is known as _____.

18. These sperm and egg contain DNA in the form of _________ .
Passing on traits
chromosomes
These sperm and egg contain DNA in the form of _________ .

19. These chromosomes contain genetic (genes) information.
Passing on traits
These chromosomes contain genetic (genes) information.

20. Genes are found in DNA. They code for the _____ organisms have.
Passing on traits
traits
Genes are found in DNA. They code for the _____ organisms have.

21. Predicting traits
Alleles: different forms of a gene (codes for trait).
Alleles occur in pairs.

22. Predicting traits
Mendel cross bred his true-breeding (homozygous) plants with differences in the same trait. `
Example: Tall vs. Short

23. Predicting traits This gave Mendel heterozygous (hybrid) offspring.
Hybrid: cross between parents with different forms of a trait
cyclins

24. Predicting traits This gave Mendel heterozygous (hybrid) offspring.
Hybrid: cross between parents with different forms of a trait
cyclins

25. Predicting traits This gave Mendel heterozygous (hybrid) offspring.
Hybrid: cross between parents with different forms of a trait
cyclins

26. How is it possible to have pea plant offspring when the genes were
Question!
