1 Offspring Inherited Trait Gene Alleles Heredity

2 Recessive Allele Dominant Allele Genotype Phenotype

3 DEF: The child or product of reproduction by plants, animals, and all other living things. DEF: A behavioral or physical characteristic that is passed from parents to their offspring. DEF: A piece of DNA that codes for a specific protein. DEF: Different forms of a single gene.

4 DEF: The passing of traits from parents to offspring DEF: The allele that is shown or expressed even if only one copy is present. DEF: The allele that needs two copies to express the trait. DEF: The combination of alleles that an organism has. This determines what trait the organism will have.

5 DEF: The physical or behavioral trait that is shown or expressed. Ff is the genotype for this trait. Having freckles is the.

6 WW, Ww, and ww are all examples of the combination of alleles for a trait, which is called the. Teacher Key: genotype The gene for pea seed color has two different forms: yellow (Y) and green (y). These different forms of a gene are called. Teacher Key: alleles R overpowers r, so it only needs one copy to express itself. This means it is the allele. Teacher Key: dominant

7 r gets overpowered by R; it can only express itself if there are two copies. This means it is the allele. Teacher Key: recessive Parents who have hitchhikers thumb can pass this trait to their offspring. Traits that are controlled by genes and passed from parents to offspring are called. Teacher Key: inherited traits

8 Each of these pieces of DNA codes for a different protein. These are examples of. Teacher Key: genes A person that has the genotype Ff would have the of freckles. Teacher Key: phenotype

9 When a plant is pollinated and it makes a seed which grows into a new plant, this new plant is the. Teacher Key: offspring The diagram shows parents passing a trait on to their offspring. This passing of traits is called. Teacher Key: heredity

10 Extras--- write Extra on the back of these cards and use only when class numbers don t divide evenly by 3.

11 Instead of having students move around the room, make one set of cards for each pair of students and store them in an envelope. Then students can sort the cards at their desk by grouping the example, definition, and word cards together for each word. Heredity Vocabulary Mix and Match Get your students moving and thinking with this quick yet effective vocabulary activity. Teacher preparation: Print all of the cards on cardstock. If printing in black and white, make a copy of the vocabulary words on one color of cardstock, the definitions on another, and the examples on a third color. If printing in color, print all cards on white cardstock. During class: Hand out one card to each student. You can easily differentiate by handing harder cards (such as the more challenging example cards) to the more advanced students. If the number of students does not divide evenly by three, give one or two students (depending on the number) one of the extra duplicate cards (see the last page of cards). Be sure to tell those students they will be in a group of four and another student will have the same card as them. Explain the activity: Students will move around the room, looking for the word, definition, and example that fit together. A complete group will have three people and three cards, each a different color, for the same vocabulary word. Once they find their group of three (or four if they have an extra card) they should move to the outside of the room so that the rest of the students can continue looking for their group. You may need to assist the last few students in finding their group. Many students also used the word wall cards with definitions (posted on the board) as a resource to help find the cards that fit with their own. Once students have found their groups, you can choose to have each group read their words, definitions, and examples or just the words to the class. If you d like to continue the activity, students can move around the room until you give the signal, trade cards with someone next to them, and find their new group of three. Repeat as many times as desired. Card Sort Variation
