Assume that blending inheritance, not particulate Mendelian inheritance, is operating in a life form.An individual with a tail that is 10 centimeters long is crossed with an individual that has a tail 2 cm long.What would the expected tail length be in the F₂ progeny? A) All individuals would have tails that are 10 cm long. B) All individuals would have tails that are 6 cm long. C) 9/16 would have tails that are 10 cm long, 6/16 would have tails that are 6 cm long, and 1/16 would have tails that are 2 cm long. D) 1/4 would have tails that are 10 cm long, 1/2 would have tails that are 6 cm long, and 1/4 would have tails that are 2 cm long. E) 3/4 would have tails that are 10 cm long, and 1/4 would have tails that are 2 cm long.

In blending inheritance, the traits of the parents blend together and are not expressed as discrete units. Therefore, the expected tail length in the F₂ progeny would be the average of the parent tail lengths, which is (10 cm + 2 cm)/2 = 6 cm.
