Which mode of inheritance does the pedigree illustrate?

This pedigree illustrates a single-gene heritable disease named oreotitis. I. .I\ IOIIIOOI a) Which mode of inheritance does the pedigree illustrate? Briefly (2-3 sentences) explain your answer. HINT: think about what type of inheritance it ISN’T as well as what type it IS. b) Define some alleles for oreotitis. C) Using those defined alleles, provide a oreotitis genotype for the individual highlighted by the arrow. 2. You have a tetrahybrid (so that’s an individual who is heterozygous for -YOU GUESSED IT – four genes) lily that has pink blooms, long stamen, round pollen, and thick roots. Each of these genes exists on different chromosomes within the genome. a) If you self-fertilize this lily plant, what are the odds that an offspring would be homozygous recessive for all four traits? b) If you self-fertilize this lily plant, what is the probability that an offspring would have long stamen with oval pollen?
