In Dexter and Kerry cattle, animals may be polled (hornless)…
Questions
In Dexter аnd Kerry cаttle, аnimals may be pоlled (hоrnless) оr horned. When many offspring were obtained from matings between polled Kerrys and horned Dexters, one-half were found to be polled Dexters and one-half polled Kerrys. When these two types of F1 cattle were bred with one another, the following F2 data were obtained: 3/8 polled Dexters, 3/8 polled Kerrys, 1/8 normal Dexters, 1/8 normal Kerrys. A geneticist was puzzled by these data and interviewed farmers who had bred these cattle for decades. She learned that Kerrys were true-breeding. Dexters, on the other hand, were not true-breeding and never produced as many offspring as Kerrys. Using symbols explain the inheritance of the traits and explain why Dexters are not true breeding.
