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.
Describe how genes are transmitted in sexually reproducing
species
Sexually reproducing species are the species that perform sexual reproduction which involves a complex life cycle. In this type of reproduction, a gamete (egg cell or sperm) with a haploid set of chromosome (n) combines with another gamete (haploid) and produce an organism with diploid set of chromosomes (2n).
In sexually reproducing species when gametes are produced then the chromosomes present in each homologous pair get segregated and transferred into the different gametes (sex cells). During the process of meiosis in sexually reproducing organisms, event of crossing over and independent assortment of the individual chromosomes contribute in the genetic diversity in population.
