- Procedure: 1. Stick a piece of masking tape on the four 25 g coins. Make sure that the size of the tape is within the circumference of the coin. For this purpose, two of Mendel's seven characters of the pea plant will be used: height and seed color. 2. Mark one side of two coins I (tall allele) and the other side t (short allele). Similarly, mark one side of the other two coins Y (yellow allele) and the other side y (green allele). 3. Monohybrid Cross. In this part, the height character will be investigated. a. Get the two coins for height: one coin corresponds to the male and the other coin to the female. T and t are gametes for tallness and shortness, respectively. b. Place the two coins in cupped hands, shake them, and toss the coins on your desk. c. Read and record the coin combinations in your data sheet. Repeat the toss 50 times. 4. Dihybrid Cross. This time, two traits will be considered: height and seed color. a. Get all four coins, place them in cupped hands, and shake and…Colored beans to represent the gene for a certain trait of garden pea. (60 pieces of the same size and shape; 30 pieces of which are of different colors from rest) Procedures: 1. Place the 30 pieces beans (one color) to one container and the other 30 pieces to the other container. Assign which color of beans will represent dominant and recessive genes of a specific trait of garden pea 2. Label the paper container as First Parent P1, male and other P1 female 3. At random, segregate the beans on the Lab table. Assume fertilization occurs and First filial generations (F1) are formed 4. Categorize the formed First filial generations 5. Put all the beans in one container. Assume that all the first filial generations undergo self-fertilization 6. Pick up the beans by two from the container without looking at it and collect the second Filial generation (F2) 7.
