Answer:
A process of change in a species over time. Interbreeding among members of a population results in. No change in the relative frequencies of alleles in the gene pool.
1. Interphase: Chromosomes duplicate
2. Prophase: Chromosomes pair up
3. Metaphase: Chromosomes line up at equator
4. Anaphase: Chromatid sisters pulled apart
5. Telophase: Cells begin to divide
6. Cytokinesis: Two daughter cells are formed
Answer:
The correct answer will be-fertilization.
Explanation:
The chromosome number in an organism is known as the ploidy level which is represented by either n or x. The organism may exhibit 1 set of chromosomes represented with n and is termed haploid and a pair of chromosomes called diploid level represented by 2n.
The organism can switch from x to 2x at the time of fertilization when separate haploid male and female gametes fuse together to form a diploid cell called zygote which further grows into an organism.
Thus, fertilization is the correct answer.
