In rabbits, spotted coat (S) is dominant to solid color (s) and black (B) is dominant to brown (b). A true-breeding black spotted rabbit is mated to a true-breeding brown solid rabbit to produce a heterozygous F1 generation. Two F1 individuals are mated, and you do not see a 9:3:3:1 (black spotted: black solid: brown spotted: brown solid) ratio of offspring, but instead see that almost all offspring are a non-recombinant phenotype. This tells you that
A. that the genes for fur pattern (spotted vs. non-spotted) and fur color assort independently. B. that the genes for fur pattern (spotted vs. non-spotted) and fur color are on the same chromosomes. C. that the genes for fur pattern (spotted vs. non-spotted) and fur color are on different chromosomes. D. that the genes for fur pattern (spotted vs. non-spotted) and fur color are epistatic. E. that fur pattern (spotted vs. non-spotted) and fur color are maternally inherited.
