Which of the following is not true about the gene inheritance All autosomal and sexual chromosomal allele pairs inherit independently Organelle genes inherit independent of nuclear genes Meiosis leads to equal distribution of all the genetic material from the genome between gametes Recombination may lead to the violation of mendelian laws of segregation None 6. Which of the following is TRUE about fertility factor F, The F+ cells are efficient donor and the F- cells are recipient F factor is a plasmid integrated into the chromosomal DNA of the bacteria F factor does not recombine with the other DNA molecules All of the above None 7. Which of the following is NOT CORRECT about the genetic recombination It takes place at the meiotic cell division Absence of meiosis in bacteria leads to no genetic recombination Genetic recombination in bacteria is through conjugation process Gene mapping in prokaryotes is similar to that of eukaryotes None 8.
