Detailed explanation-1: -Sexual reproduction involves formation and fusion of gametes. This results in the formation of zygote which develops to form embryo.

Detailed explanation-2: -During fertilization, the sperm and egg unite in one of the fallopian tubes to form a zygote. Then the zygote travels down the fallopian tube, where it becomes a morula. Once it reaches the uterus, the morula becomes a blastocyst.

Detailed explanation-3: -The result of karyogamy is the formation of a diploid cell called the zygote or zygospore. This cell may then enter meiosis or mitosis depending on the life cycle of the species.

Detailed explanation-4: -Fertilization results in the formation of zygote. The male gamete cell (sperm) and female gamete cell (egg) fuse together to form a zygote. Zygote divides repeatedly to give rise to balls of cells.
