Answer the following question given this paragraph: 

During sexual reproduction, two parents are involved. Most animals are dioecious , meaning there is a separate male and female sex, with the male producing sperm and the female producing eggs. When a sperm and egg meet during fertilization , a zygote , the first cell of a new organism, is formed ( Figure below ). This process combines the genetic material from both parents. The resulting organism will be genetically unique. The zygote will divide by mitosis and grow into the embryo.


Q: In dioecious animals, females generally produce what contribution to reproduction?


A:
eggs
