I. OBJECTIVES At the end of the activity, the students are able to: A observe the separation and independent assortment of alleles: B. demonstrate the inheritance of dominant and recessive traits, codominance. and incomplete dominance: and C. construct a model of a dragon based on the characteristics inherited from the parent dragons. II. MATERIALS Writing materials 2 Five-peso coins 2 One-peso coins 2 Twenty-peso coins Ill. PROCEDURE I. In this activity. you and a partner will work together to produce o baby dragon from the random mixing of genetic traits. Each student will be a surrogate dragon parent. Surrogate dragon parent partners must be of the opposite sex. therefore the female has X/X chromosomes white the male has X/Y chromosomes. You can ask your parent. sibling. or relative to work with you Or you Can work with your Classmate. 2. Each partner must have three different coins -- one of each color of autosome (green and yellow autosomes). and one sex chromosome coin_ You can use the one-peso coin for green outosome. the five-peso coin for yellow outosome. and the twenty-peso Coin for sex chromosome. Each side Of a coin represents a chromosome, and the Iwo sides together represent a pair of homologous chromosomes. 3. Refer to the alleles of each parent in the chart in data and results. Identify dad and mom's phenotype using the dragon genome table below and record it under mom and dad's trail in the data and results table. 4. For each color autosome and then for the sex chromosomes. each parent will randomly toss his or her coin on the table. The side of the coin that is up represents the chromosome that is passed on to the baby. It it is head, your baby will inherit allele I. If it is tail your baby will inherit allele 2. You and your partner will do this in an the traits listed in the table under data and results to determine the homologous (the next step is in the photo provided, please complete the table) General Biology 2 (STEM 11)Page 9 of 10 pagesIV.

in the egg and sperm columns in the chart in data and results.
5. Next, you must decode the genes inherited by your bundle of joy to determine the
phenotype of your baby. Record the trait produced by each pair of alleles in the
Baby's Traits column of the chart in data and results. If your baby dragon is aa , be
sure to take this into account when assessing the phenotypic effects of the skin color
and freckles genes. Remember that a CAPITAL letter is dominant over a small letter
(recessive) unless the decoding chart indicates those traits are codominant, sex-
influenced, or have incomplete dominance.
6. Using the picture below, you may trace or freehand draw the traits to produce your
baby dragon's picture. If your baby dragon has them, draw in extra toes, freckles,
and/or skin color (or label the color). You can color your baby dragon.
