Create a Punnett square for this cross and present the expected phenotypic ratio. 2.) Present your results in a table as dihybrids and determine the observed phenotypic ratio of purple/smooth to purple/shrunken to yellow/smooth to
Bacterial Genomics
The study of the morphological, physiological, and evolutionary aspects of the bacterial genome is referred to as bacterial genomics. This subdisciplinary field aids in understanding how genes are assembled into genomes. Further, bacterial or microbial genomics has helped researchers in understanding the pathogenicity of bacteria and other microbes.
Transformation Experiment in Bacteria
In the discovery of genetic material, the experiment conducted by Frederick Griffith on Streptococcus pneumonia proved to be a stepping stone.
Plasmids and Vectors
The DNA molecule that exists in a circular shape and is smaller in size which is capable of its replication is called Plasmids. In other words, it is called extra-chromosomal plasmid DNA. Vectors are the molecule which is capable of carrying genetic material which can be transferred into another cell and further carry out replication and expression. Plasmids can act as vectors.

DIHYBRID CROSS
1. ) Consider the possibility that your observational data are of plants
resulting from a dihybrid cross, where the previous generation were heterozygous
for both traits (RrSs x RrSs). Create a Punnett square for this cross and present
the expected
2.) Present your results in a table as dihybrids and determine the observed
phenotypic ratio of purple/smooth to purple/shrunken to yellow/smooth to
yellow/shrunken. Consider the plant as a whole rather than the individual cobs.
