Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When two haploid cells unite to form a diploid cell, what is this process called?
A
Mitosis
B
Spermatogenesis
C
Zygote
D
Fertilization
Explanation: 

Detailed explanation-1: -Meiosis is where a diploid cell gives rise to haploid cells, and fertilization is where two haploid cells (gametes) fuse to form a diploid zygote.

Detailed explanation-2: -Fertilization is the process in which haploid gametes fuse to form a diploid cell called a zygote.

Detailed explanation-3: -When a sperm fertilizes an egg, the genetic material is combined in the resulting zygote cell. In other words, a single set of chromosomes in two separate haploid cells come together as two sets of chromosomes in a single diploid cell. That zygote cell ultimately undergoes development into a new person.

Detailed explanation-4: -Fertilisation is the process of merging of two haploid cells to form a diploid cell. Human fertilisation is the union of a human egg and sperm to form a zygote (diploid cell).

Detailed explanation-5: -Sexual reproduction involves two parents and produces offspring that are genetically unique. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote.
