During fertilisation in living beings, fusion of male and female gametes takes place to form a cell called:

zygote

The correct answer is Option (1) - zygote

During fertilization in living beings, fusion of male and female gametes takes place to form a cell called:Zygote

The zygote is the single-celled organism that results from the fusion of a sperm cell (male gamete) with an egg cell or ovum (female gamete) during fertilization. The zygote contains a complete set of chromosomes, half from the sperm and half from the egg, and it marks the beginning of the development of a new individual. The zygote undergoes rapid cell division, leading to the formation of an embryo, which further develops into a multicellular organism.
