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.

Figure 1.6. The number of ascospores in non-recombinant and recombinant asci.
In the non-recombinant asci all 8 ascospores are non-recombinant (see Figure 1.6 above). In the non-recombinant asci 4 of the
ascospores are recombinant and 4 of the ascospores are non-recombinant (see Figure 1.6 above). To determine how many recombinant
and non-recombinant ascospores where in the two pictures above we need to do the math below. You need to use the total number of
non-recombinant asci and the total number of recombinant asci that you counted in the pictures above.
# of non-recombinant ascospores = 8 x total number of non-recombinant asci + 4 x total number of recombinant asci
# of recombinant ascospores = 4 x total number of recombinant asci
Total # of ascospores = # of non-recombinant ascospores + # of recombinant ascospores
Calculate the number of non-recombinant ascospores, recombinant ascospores, and total number of ascospores using the equations
above and choose the correct answer below.
