AP Biology Period 2 #WongNation

Devansh Taori Biology AP Period 2 Mr. Wong Conclusion In this experiment, we analyzed two types of crosses within corn plants – monohybrid and dihybrid crosses. In monohybrid crosses, the parent plants differ with respect to only one trait. However, for dihybrid crosses, the parent plants differ with respect to two traits. In the monohybrid cross, the probable parent genotypes for color were Pp and for texture were Ss. According to probability theory, the expected % of dominant to recessive traits was 75% to 25%. We indeed did find this when looking at our results – 173 were purple (dominant), and the other 64 were yellow (recessive) – that's 73% to 27%. 184 were smooth (dominant), and the other 53 were shrunken (recessive) – that's 78% to 22%. Thus, looking at results, it's clear to see that in the monohybrid cross, the offspring displayed their traits in accordance with standard Punnett Square probability theory. In the dihybrid cross, however, the optima
