the second results of purple stem and yellow-green leaves. The purple stem and yellow- green leaves came out to be around 22 plants, which is more than expected which was 18. The green stem and dark green leaves is dominant from the yellow-green leaves, because observed was 18 and the expected was 18. And lastly, green stem and yellow-green leaves were last which observed were four plants and the expected were six. Overall the class results came in very close with the expected numbers given in the lab Manuel. Also part of the experiment the Chi-squared statistical analysis was used, which is an analysis used to investigate whether the distribution of variable are different from one another. The chi-squared was given in the lab manual; Table 14.1.
TABLE {2}: Final Results # Phentotype (stem,leaf) # Observed # Expected O-E (O- E)^2 (O-E)^2/E 1 Purple, dark green 50 53 3 9 .16 2 Purple, yellow- green 22 18 4 16 .88 3 Green, dark green 18 18 0 0 0 4 Green, yellow- green 4 6 -2 4 .67 SUM 94 X^2 SUM 1.71 Conclusion: During this experiment Brassica rapa plant seeds were planted and thoroughly observed throughout the entire semester. The phenotype of the plants began to appear within four to five days from planting and within two weeks the phenotypes were confirmed. Only two genetic traits were observed and those are the leaf color and the stem color. For this particular plant, the leaf color green, is dominant over yellow-green and the stem color purple, was dominant over the green stem. The ratio of the phenotype of the punnett square is 9:3:3:1 and the class experiment reached closely to the stated ratio. According to table 2 of the results, the lab class results were very close to the
expected numbers of the experiment. This experiment was also conducted to understand the genetic events taking place during gametogenesis and fertilization. Both were equally important to understand the transmission genetics in sexual reproduction of diploid organisms.
