What is a Fertilized Egg Called?

Answer – A fertilized egg is commonly called a “zygote.”

Explanation: 

A zygote is a single cell resulting from the fusion of a sperm (a male gamete) and an egg (a female gamete) during sexual reproduction (fertilization) in organisms. It is the initial stage of an organism’s development and contains the combined genetic material from both the sperm (paternal) and the egg (maternal). The zygote then undergoes cell division and differentiation, eventually leading to the development of an embryo.
