Formation of a Fertilized Egg Gametes are formed by meiosis Egg (n) – Ovary Sperm (n) - Testis –gametes join together in the _Zygoteforming a Restores the Chromosome Number (2n)

Sperm + egg zygote.

Explanation:

During sexual reproduction, a male sperm fuse with female eggs forming a new organism. Male sperm and female eggs have haploid number of chromosomes but when they fuse with each other a zygote will formed having diploid number of chromosomes. The gametes of male and female have haploid number of chromosomes due to meiosis cell division.

the cell cycle is the final answer! : )

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
