Give typing answer with explanation and conclusion Consider a pair of homologous chromosomes heterozygous for three genes (e.g. ABC / abc) during prophase I of meiosis. Let the sister chromatids of one homolog be numbered 1 and 2; and the sister chromatids of the other homolog be numbered 3 and 4. A crossover that would result in genetic recombination (e.g., Abc or aBC) could involve which chromatids? a. 1 & 2 or 3 & 4 b. 1 & 3 or 2 & 4 c. 1 & 4 or 2 & 3 d. 1 & 3 or 1 & 4 or 2 & 3 or 2 & 4 e. any two of the four chromatids
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.
