#Question id: 4809


The upper most following figure above shows the locations of four genes on the genetic map of an organism; the lower figure shows the locations of the same four genes on a physical map derived from the nucleotide sequence of the DNA of that organism. The maps are not identical because

#Part-A Aptitude & General Biotechnology
  1. There is no relationship between the position of genes in a genetic map and their positions on the DNA

  2. recombination frequencies per kb of DNA are not uniform throughout a chromosome

  3. the farther apart two genes are, the more likely they are to recombine

  4. some genes contain introns
