It doesn't normally happen but has been known, and cygnets have been produced.
the swan had seven cygnets
The color of cygnets, whether grey or tan, is primarily determined by the species of swan and genetic factors. For instance, mute swan cygnets typically start out grey, while other species, such as the trumpeter swan, may have tan or lighter-colored cygnets. Environmental influences and individual variation can also play a role in the exact shade of a cygnet's down feathers.

Cygnets are the offspring of Swans. So a cygnet will become a swan.

The mute swan has an orange beak once fully adult, as compared to the other two species native to the UK, the Bewick and the Whooper swans. The Bewick has a predominantly yellow beak and the whooper has a black beak with a strong yellow triangular section. When cygnets, the mute swan is grey in colour and has a black beak which only becomes orange after losing its cygnet feathers and reaching maturity.
Both the mother and father swan work together to care for their young. The mother usually sits on the nest and protects the eggs, while the father helps to guard the nest and may assist in raising the cygnets once they hatch.
A dad swan is commonly referred to as a "cob." In contrast, a female swan is called a "pen." Together, they typically form a family unit, raising their cygnets, or young swans, together. The terms "cob" and "pen" are most often used in relation to mute swans, but they can apply to other swan species as well.
A young swan is called cygnets.
