Figure 1. Showing a homologous pair of chromosomes that carry two linked genes. Here we can see that one chromosome carries A and B alleles, while the other homologous chromosome carries a and b alleles. This is much more informative than just giving the genotype of AaBb. Another way to symbolize the arrangement of alleles on a chromosome is to give the symbols for alleles on one chromosome above a horizontal line, and the symbols for the alleles on the homologous chromosome below the horizontal line. For example: A b Figure 2. Showing the arrangement of alleles for a pair of linked genes. Here we can see that, exactly like the example in Figure 1, one chromosome carries A and B alleles, while the other chromosome carries a and b alleles. 1. Suppose that Gene G and Gene D are linked. If the genotype of an organism is GRDD, use both types of symbols you learned in Figure 1 and Figure 2 above to show the arrangement of alleles for this organism. %23
