Exercise 3 Modeling Meiosis In this exercise, you will create models to simulate the stages of meiosis in an animal cell. Procedure 1 Gather the chromosome kit, 2 sheets of white paper, 2 sheets of black paper, cut pieces of drinking straw from Exercise 1, scissors, tape, and the digital camera. 2 Create the cell body by taping 2 sheets of white paper together. 3 Create 4 nuclei by cutting 4 circles from the black paper, approximately 6" in diameter. 4 Create a set of chromosomes ("original" and "duplicated"), as shown in Table 3. When building the chromosomes, the white magnetic tube represents the centromere, while the beads extending from the centromere represent the arms. Note: The colors and numbers of beads per arm is the same as created in Exercise 1. Chromosome Color Number of beads per arm Label 1 Red 4 2 Red 4 3 Red 3 4 Red 3 5 Yellow 4 6 Yellow 4 7 Yellow 3 FFFFMME 8 Yellow 3 M Table 3. Chromosomes with Labels 5 Use the marker to label the chromosomes with an M (for mother)…

Observation 1: 1 out of 2 first trimester abortuses show abnormal karyotypes with 96% caused by numerical abnormalities and 4% with structural abnormalities. At live birth, 1 out of 160 has abnormal karyotypes with 60% caused by numerical changes. This number increases with fetuses of mothers over 35 years old to 1/50 for total incidence and 85% for numerical changes. Questions: Think of reasons why it is important to maintain the number and structure of chromosomes. Why is maternal age so important?
