Genetic Linkage: Inheritance of Genes Near Each Other on the SameChromosomeIn this activity you will study the patterns of inheritance of multiple genes in (imaginary) dragons. These dragons are diploid and they have only two pairs of homologous chromosomes in each cell. You will see that the patterns of inheritance are determined by the behavior of chromosomes during meiosis and fertilization. We will consider three genes on Chromosome 1 and one gene on Chromosome 2, as indicated in the following table.Dominant AllelesRecessive AllelesChromosome 1W = has wingsw = no wingsF = fire-breathingf = no fire-breathingN = long fangsn = short fangsChromosome 2H = big hornsh = small hornsFor this activity, the father is heterozygous for each of these genes (WwFfNnHh), and the mother is homozygous for the recessive alleles (wwffnnhh). For the sake of simplicity, we will assume all genes are simple dominant/recessive and have complete penetrance. For the three genes on chromosome 1 for the father, the dominant alleles
