14. In guinea pigs, brown fur is dominant over white. Two guinea pigs mate and half of their offspring are brown and half are white. What are the genotypes of the parents?

15. The ability to taste PTC is dominant. If two heterozygous tasters have children, what percentage will be non-tasters?

16. In rabbits, brown is dominant over white. If two rabbits mate and have 30 brown offspring and 10 white offspring, what are the genotypes of the parents?

17. A red flower and a white flower produce pink offspring. What type of inheritance is this?
If two pink flowers cross-pollinate, what will be the phenotypic ratio of the offspring?

18. A white cow and a red cow produce roan offspring. What type of inheritance is this?
What two parents would make the highest percentage of roan offspring?

19. If offspring inherit an allele for curly hair, and an allele for straight hair, their hair is wavy. What type of inheritance is this?
If a woman with wavy hair mates with a man with straight hair, what percentage of their
offspring will have straight hair?
