The equations summarize the process of fertilization. Which equation represents fertilization? haploid + diploid = diploid
diploid + haploid = haploid
haploid + haploid = diploid
diploid + diploid = diploid

Answers

The answer is haploid + haploid = diploid.

Fertilization is the process in which two gametes (one male and one female) fuse which first creates a zygote and then leads to the development of an embryo. Germ cells are cells that give rise to the gametes - either egg cells (female gamete) or sperm cells (male gamete). Germ cells are the only cells that can undergo both mitosis and meiosis. They are diploid cells present in gonads. After meiosis haploid gametes are produced. Thus, in fertilization two haploid gametes fuse (n+n) and form diploid zygote (2n).

Answer:

C) haploid + haploid = diploid
