a.
To determine:
(a) Whether Cuenot’s results are significantly different from the 3:1 ratio that he thought he observed. Also determine are they different from the 2:1 ratio. (b) Whether Castle and Little results are significantly different from the 3:1 ratio. Are they different from the 2:1 ratio. (c) Whether the results of Castle, Little, and Cuenot when combined, are significantly different from the 3:1 ratio and a 2:1 ratio. (d) Suggest an explanation for the different ratios that Cuenot, Castle, and Little obtained.
Introduction:
Mice are the most commonly used models for the laboratory testings. The coat colors of the mice are generally white, agouti, yellow, and black. These coat colors are the Mendelian traits. The coat color of the mice is controlled by many different genes such as the gene C that causes pigmentation in the fur, the gene B that permits black pigmentation, the gene A that causes yellow pigment deposition near the tips of the hairs, and the gene D that has no effect in the coat coloration.
