Some mice have either a kinked tail or a normal tail. Kinked tails (K) are dominant. Located on another chromosome is the gene for growth. This gene can either be dominant, causing
normal growth (N), or it can be recessive (n), causing obesity in the mouse. Two mice that are
heterozygous for a kinked tail and heterozygous for normal growth are crossed. What is the
phenotype ratio resulting from this cross?
