Phenotype of the Offspring and Genotype,

# Introduction
This try is examining the disembodied spirit speech rhythm of a typical unfolding plant in a short period and analyzing the genetic constitution of the pargonnts through the phenotype their off spring. The wild mustard Brassica rapa is employ for this experiment. Fast plants admit a very rapid life cycle. Brassica flowers within 13~18 days, and they sewer breed at high densities under bright, cool-white fluorescent lighting. at that place are two purpose of this experiment: observing the life cycle of the typical flowering plat, and learning genetic of plant and how they can be inherited. Referring to the lab manual on page 7-21, homozygous (ANL/ANL) or heterozygous (ANL/anl) for the dominant anthocyanin gene ANL lead have a lofty stems. Therefore, the plant will produce anthocyanin. On the other hand, homozygous (anl/anl) for the recessive anthocyaninless mutant gene anl will have white or green stems. Each of the purple and green plants of the F2 generation, generated by seeds which obtained cross-pollination will be counted. Hence, Mendelian genetics can be explained by the ratio between anthocyanin (purple) and anthocyaninless (green).



There are six possible agnatic crosses in this experiment and the genotype of the parents can be deduced by the ratio of the phenotype of their subject if the anl gene segregates in a Mendelian fashion. Four varied ratios by using the Punnett Squares are used to deduce the parental genotype. For example, if the ratio of purple stem to green stem is 3:1(ANL/ANL, ANL/anl, ANL/anl, anl/anl), the genotypes of both parents are heterozygous ANL/anl. Finally, the hypothesis will be tested that the phenotype of the offspring can be used to take root the genotype of the parents since the recessive mutant allele anl segregates in a simple Mendelian fashion.
# Materials and Methods
The first step, we took four Brassica seeds from put up 1 and planted them in two of the four cells in a quad then four seeds of Parent 2 were planted in each of the...If you want to get a full essay, order it on our website: Ordercustompaper.com
