MONOHYBRID CROSS 1. Present the data as monohybrids (Xx, XX, xx) for all five corn cobs and for the plant. Present the colour and texture phenotypes with their associated genotypes in separate tables. Your first table should include the corn ID, the number of purple kernels, the number of yellow kernels, and the phenotypic ratio between the two kernel colours. Present the texture results in the same format to a separate table. 2. What is the dominant phenotype for kernel colour in your assigned corn plant? What is the dominant phenotype for kernel texture in your assigned corn plant? 3. What are the probable phenotypes for the previous generation of corn plants with regard to kernel coloration?
Genetic Recombination
Recombination is crucial to this process because it allows genes to be reassorted into diverse combinations. Genetic recombination is the process of combining genetic components from two different origins into a single unit. In prokaryotes, genetic recombination takes place by the unilateral transfer of deoxyribonucleic acid. It includes transduction, transformation, and conjugation. The genetic exchange occurring between homologous deoxyribonucleic acid sequences (DNA) from two different sources is termed general recombination. For this to happen, an identical sequence of the two recombining molecules is required. The process of genetic exchange which occurs in eukaryotes during sexual reproduction such as meiosis is an example of this type of genetic recombination.
Microbial Genetics
Genes are the functional units of heredity. They transfer characteristic information from parents to the offspring.

MONOHYBRID CROSS
1. Present the data as monohybrids (Xx, XX, xx) for all five corn cobs and
for the plant. Present the colour and texture
genotypes in separate tables.
Your first table should include the corn ID, the number of purple kernels, the
number of yellow kernels, and the phenotypic ratio between the two kernel
colours.
Present the texture results in the same format to a separate table.
2. What is the dominant phenotype for kernel colour in your assigned corn
plant? What is the dominant phenotype for kernel texture in your assigned corn
plant?
3. What are the probable phenotypes for the previous generation of corn
plants with regard to kernel coloration?
4. What are the probable phenotypes of the previous generation of corn
plants with regard to kernel texture?
