A comparative chromosome map of birds and mammals inferred human homologies (right numbers) on chromosome ideograms. a. Reconstructed karyotype of the ancestral Eutherian genome. Each chromosome is assigned a specific color. These colors are used for mark homologies in ideograms of chromosomes of other species (Figure 5b-5i) b. Ideogram of chicken (Gallus gallus domesticus, 2n = 78) chromosomes. The reconstruction is based on alignments of chicken and human genome sequences. c. Ideogram of short-tailed opossum (Monodelphis domestica, 2n = 18) chromosomes. The reconstruction is based on alignments of opossum and human genome sequences. d. Ideogram of aardvark (Orycteropus afer, 2n = 20) chromosomes. The reconstruction is based on painting data. e. Ideogram of mink (Mustela vison, 2n = 30) chromosomes. The reconstruction is based on painting data. f. Ideogram of the Red fox (Vulpes vulpes, 2n = 34 + 0-8 B's) chromosomes. The reconstruction is based on painting and mapping data. g. Reconstructed karyotype of the ancestral Sciuridae (Rodentia) genome, based on painting data (Li et al., 2004). h. Ideogram of the House mouse (Mus musculus, 2n = 40) chromosomes. The reconstruction is based on alignments of Mus and human genome sequences. i. Ideogram of human (Homo sapiens, 2n = 46) chromosomes.
