Fast Plants Lab Report Mendelian Genetics I: Fast Plants By Neil Sarker Biology 113 March 09, 2018 Lab Partners: Amanda Shkreli Kvita Kravchyk Will Kulp
Fast Plants Lab Report ABSTRACT The experiment will test the inheritance of genes of homogenous plants through cross of genes with many traits. The first experiment is about anthocyanin is inherited due to Mendel’s Laws and having anthocyanin is a dominant trait. For experiment two, traits are controlled by two different genes, anthocyanin and leaf color are both dominant traits. Part three of the experiment follows Mendel’s Laws and dominant traits. The conclusion for experiment one is that the anthocyanin is inherited due to Mendel’s laws is there for being dominant trait. The results of experiment 2 concluded that anthocyanin and leaf color were both dominant traits. The results of experiment 3 concluded that variegation was more dominant. INTRODUCTION Mendel formulated the laws of segregation and independent assortment, which explained the inherited genes of the offspring from their parents. Mendel’s law of segregation claimed that alleles split into individual chromatin. Mendelian genetics is not the only way in which genes can be inherited. Certain traits can be inherited on the sex chromosome in which individuals receive from their parent, this is known as sex linkage. While Mendelian inheritance of genetics took place in the nucleus ( during mitosis and meiosis), cytoplasmic inheritance takes place in the cytoplasm. We used a plant for this experiment in order to speed up the process and a to have the ability to control the different pollinations. We used the Brassica rapa fast plant, this plant was used because of its short lifespan of about 40 days. This allowed us to keep the experiment to be administered within a short time frame. The fast plant contained three traits, characteristics of
Fast Plants Lab Report anthocyanin, leaf color and variegation. Anthocyanin, which is a dominant trait, is a purple color that appears on the stems of the plants and act as a sunscreen to protect against the harsh rays of the sun. there are two different types of phenotypes for this trait, they are anthocyanin present and anthocyanin absent.
