In linkage mapping, how do we measure the distance between genes on a chromosome? options: A) The number of gametes used is proportional to the percent recombination in offspring. B) The number of offspring produced is equal to the percent recombination during crossover. C) The number of chromosomes resulting from crossover is equal to the distance the genes are apart in any one gamete. D) The percentage of recombinant offspring is directly proportional to how far apart the genes are on the chromosome.
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.
