Answer:
fertilization.
Explanation:
During fertilization, male and female gametes are fused to form a zygote. The male gametes in humans are called sperms. Sperms are formed by meiosis in sperm mother cells and have a haploid number of chromosomes (n=23). Similarly, the female gamete in humans is an egg which is a product of meiosis and is haploid (n=23). The fusion of these two haploid cells occurs in the oviduct of females in humans and form the diploid zygote with 2n=46. This process is called fertilization.
The process, which creates 47 chromosomes in the given question is known as non-disjunction.
Non-disjunction
It is a phenomenon in which the pair of homologous chromosomes has failed to separate at the time of cell differentiation, such that both the chromosomes go to one of the daughter cell and none to the other one.
It results in errors in chromosome number like trisomy 21 also known as Down syndrome.
Trisomy is characterized by an additional chromosome, that is, an individual with trisomy possess 47 chromosomes in place of 46.
Thus, the process is known as non-disjunction.
