A pedigree diagram follows a recessive coat characteristic through three generations of rabbits. Which statements about what the diagram shows are true? Select all that apply.

توضیح

What is drawn is what could be observed in each animal, so the shading follows appearance and stops there. Because a single dominant allele is enough to hide a recessive one, an animal drawn unshaded may hold a recessive allele that no symbol on the diagram is able to reveal.
