On a fox ranch in Wisconsin, a mutation arose that gavea “platinum” coat color. The platinum color proved verypopular with buyers of fox coats, but the breeders couldnot develop a pure-breeding platinum strain. Every timetwo platinums were crossed, some normal foxes appeared in the progeny. For example, the repeated matings of the same pair of platinums produced 82 platinumand 38 normal progeny. All other such matings gavesimilar progeny ratios. State a concise genetic hypothesisthat accounts for these results.

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
