2. Each partner must pick up five Popsicle sticks -- one of each color of autosome, and one sex chromosome stick. Each side of a stick represents a chromosome, and the two sides together represent a pair of homologous chromosomes.

3. Each parent will list his/her genotype on the chart of “Our Baby” under the appropriate MOM or DAD column. (ie. If the mother dragon had “F” on one side of the red autosome and “f” on the other, that parent would write “Ff” in the first box of the MOM column.) 4. For each color autosome and then for the sex chromosomes, each parent will randomly drop his or her stick on the table. The side of the stick that is up represents the chromosome that is passed on to the baby. 5. The alleles from each pair of homologous chromosomes will be recorded in the data chart of “Our Baby” under the “Alleles in egg/sperm” columns. 6. The decoding chart on the next page indicates the phenotypic effect of each gene. The trait produced by each pair of alleles should be recorded in the data chart. Remember that a CAPITAL letter is dominant over a small letter [recessive] unless the decoding chart indicates those traits are codominant, sex-influenced, or sex-limited. 7. The students will then use the list of traits to draw the dragon baby. Students may use the picture page provided in the classroom as a guide, if needed. 8. Students will identify the genotypes of each trait by labeling it with the symbols for each trait (27 total) and then check off on the “Our Baby” chart that the trait is labeled.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
