A class of chemicals that are used to soften plastics like PVC, function as fixatives and solvents and bind fragrances in the products are known as phthalates. The human encountering with the chemicals can take place via:
1. Inhalation of fragrances or fumes from fixatives and solvents,
2. Chewing on a plastic toy by a child that develops small openings in the plastic, which provides a space for the chemical to get leached from the toy into the mouth of the child.
3. Through the absorption of perfumes, lotion, and deodorants.

Letters are the easiest way of modeling a Punnett square. The big letters mean it's dominant, while the lower case means it's recessive. Dominant traits will show up over the recessive traits. The answer is 75% because if the female is heterozygous, her alleles would be Ll, and as I said before, the big letters take over the little letters in any case.
