Give the probable genotypes of the parents if they produced the offspring listed after the following crosses: (a) Colored normal ? white waltzer produced 10 colored normal, 8 colored waltzers, 2 white waltzers, and 11 white normal. (b) Colored normal ? white normal produced 35 colored normal and 13 colored waltzers. (c) Colored normal ? colored normal produced 37 colored normal, 14 colored waltzers, 9 white normal, and 5 white waltzers. What will be an ideal response?
