Let's take the example of the gray kangaroo (Macropus fuliginosus) whose ploidy is 8 and the sexual determinism of this species is carried out according to the XY mode. From a male kangaroo: a) Draw the karyotype of this individual, obtained by stopping division at metaphase. Your drawing should include: a. All maternal and paternal chromosomes involved (different colors) b. An example of autosome and heterochromosome c. An example of homologous chromosome, sister chromatid and centromere. d. The total number of chromosomes in a metaphase kangaroo cell. e. A sentence to explain the difference between the terms gene and allele that might apply to this species. N Page 3 / 4
