a) What do you notice about the amounts of recombination in the various species? b) This paper found that recombination is positively correlated with gene density (number of genes per kb of chromosome) and negatively correlated with the density of repetitive elements (areas of the genome that are repetitive and do not encode genes). Why might this be the case? c) A cross was made between two individuals (AaBhxAaBb) where A codes for red eyes, a codes for blue eyes, B codes for curly wings, and b codes for straight wings and the following offspring were observed. 11 offspring with red eyes and curly wings 2 offspring with red eyes and straight wings 1 offspring with blue eyes and curly wings 2 offspring with blue eyes and straight wings Does this follow Mendelian genetics? If not, what (genetically) might explain the data?
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.
