I have two hard genetics questions need help?

3) A hybrid gray mouse is mated with a white mouse. If they have 13 offspring, explain the offsprings phenotypes and genotypes?



4)When a snapdragon which is purebred for red flowers is crossed with one purebred for white flowers, the offsprings are pink. Predict the results of combining a pink flower with a purebred red one?





please no smart remarks if u can
