In pigeons, the allele for normal feathers (F) is dominant to the allele for frizzy feathers (f). If a purebred, normal-feathered bird is crossed with a frizzy feathered bird, what percentage of the offspring will possess normal feathers?

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
