The Mode of Inheritance in Nicotiana Tabacu seeds and Albinism
Introduction
In plants, the chloroplast is an essential organelle for a plant cell’s primary metabolism. Productions such as CO2 fixation, manufacture of carbon skeletons and fatty acids, and synthesis of amino acids from inorganic nitrogen that is important for a plant to live and thrive. (Liu, Li, & Cheng, 2016) In addition, the chloroplast is responsible for producing the color pigment in plants because chloroplast produces a chemical called Chlorophyll. The chlorophyll is caused by a process cause photosynthesis that happens in chloroplast.
Chloroplast biogenesis is a process where photosynthetic pigments are biosynthesized. Light is therefore one of the …show more content…
The second primary literature was done by Lyn A. Gettys and David S. Wofford, it was an experiment that was about understand the genetic control of albinism in Pickerelweed.
In comparison, albino plants lack chlorophyll in their chloroplast and are therefore non-photosynthetic. Non-photosynthetic means that the plant itself cannot make the nutrients and energy it needs to grow and therefore albino plants do not survive. The phenomenon of albinism has interested researchers for years and inheritance of the mutation has been described in a number of species. Albinism may be controlled by a single locus or by multiple loci, but this lethal trait is necessarily recessive to normal green leaf production (Gettys and Wofford, 2007).
In lab, my partners and I performed a similar experiment with Nicotiana Tabacu, which is a cultivated tobacco plant. The purpose of that experiment was to sort through the tobacco plant seedlings and record their phenotype based off of the different color …show more content…
After counting the total number of seeds, we then organized the seeds into three different phenotypes and counted the total for each phenotype. For our data, we recorded our final observations which was 14 yellow,16 light green, and 19 dark green tobacco plants.
Phenotype # of Seedlings Percentage
Yellow 14 28.60%
Light Green 16 32.70%
Dark Green 19 38.70% Total: 49
