Abstract
The Wisconsin Fast Plants, Brassica rapa, are an ideal model organism for exploring patterns of inheritance and phenotype expression due to their rapid life cycle and observable traits. In this experiment, we examined the controlled crosses between the two phenotypes, anthocyanin-producing (ACN) and anthocyaninless (ANL), to observe allele inheritance. We observed phenotypes in the F1 generation to see if it followed the Mendelian inheritance patterns of homozygous dominant. By planting and watering the plants for two weeks, we tracked their growth and traits of ACN and ANL phenotypes. We used honey bees to cross pollinate the parent ACN and ANL plants. The seeds grown were then used to analyze the F1 generation to determine whether the ACN allele was either homozygous or heterozygous. The F1 generation had a count of 70 ACN and 52 ANL plants, which came out to be 57.4% and 42.6%, respectively. The chi-squared test determined that the p-value was 0.248. Since we got a 50-50 ratio of ACN and ANL phenotypes in the F1 generation, we can determine that the parent ACN allele was heterozygous.
