Describe the function of the centromere. How are centromeres different from other regions of the chromosome?
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

5) Suppose that in a species of flowering plant, we cross a plant with red flowers with a short stem with a
plant with blue flowers with a long stem. The offspring all have mauve flowers and a long stem. The two
characters, flower color and stem length, are found on different chromosomes.
What can you conclude about the mode of inheritance of each of the characteristics of this plant
species? Incomplete dominance or codominance: C"C", simple A/a dominance
b
If a progeny with long-stemmed mauve flowers from FI is crossed with a plant with
short-stemmed mauve flowers, what proportion of the progeny will have the same genotype as
either of the parents? Compulsory Punnett grid.

- ● ● Illustrate the chromosome changes in interphase and mitosis using a diploid cell that is 2n=4 (two large and two small chromosomes). Label the circles as G1 and G2 stages of interphase and each phase of mitosis (in order). Draw the chromosome in each circle using the following guidelines. 1) For unreplicated chromosome draw a line (/) and for replicated chromosome draw an X. 2) For simplicity, do not indicate that the chromosomes are decondensed chromatin during interphase. 3) Skip drawing the nuclear membrane or spindle fibers, since we are focusing on the chromosomes. Label genes in the resulting daughter cells as A/a and B/b. (These letters represent genes which are at particular places along the DNA molecule. Each chromosomes can have a thousand genes but we are focusing on these two.)
