66. What is the difference between a autosomal genetic disorder and a sex-linked (X-linked) disorder?
67. Compare and contrast mitosis and meiosis.
68. In tomatoes, the texture and color of the skin matter a great deal. The smooth texture (S) is dominant to
the peachy texture (s) and the red color (R) is dominant to yellow ( r ). The Pittston variety has tomatoes
that are smooth and red in color, but the Wyoming variety has the not so popular smooth and yellow in
color. So, complete a dihybrid cross between a Pittston tomato that is heterozygous for both traits and a
Wyoming tomato that is heterozygous smooth and yellow in color. Determine the phenotype ratio
