Gametes, such together eggs and also sperm, room haploid reproductive cells the fuse throughout fertilization in sexual life cycles.

You are watching: Which event makes meiosis a reductional division and why?


Which declare correctly defines a key difference between cells beginning prophase of mitosis versus prophase i of meiosis?
For cell entering mitosis, homologous chromosomes duty independently; for cells entering meiosis, homologous chromosomes pair up.
What effect do meiosis and fertilization have actually on the ploidy level that cells produced by every process?
Meiosis decreases the ploidy level native 2n to n; fertilization increases the ploidy level indigenous n to 2n.
Meiosis creates gametes (eggs and sperm) with just a solitary chromosome collection (haploid or n) indigenous parental cells through two chromosome sets (diploid or 2n). During fertilization, the haploid sperm (n) and egg (n) fuse, creating a diploid zygote (2n). The cell of the zygote then division by mitosis (which walk not readjust the ploidy level) to develop an adult biology (still 2n) of the next generation.In sexual life cycles, meiosis and also fertilization keep the number of chromosomes constant from generation come generation.
Which statement is correct worrying the relationship between chromosomes and chromatids?A replicated chromosome includes a solitary chromatid. One unreplicated chromosome contains a single chromatid. One unreplicated chromosome contains two sister chromatids. A replicated chromosome has two sisters chromatids.
A replicated chromosome consists of two sisters chromatids.A replicated chromosome consists of two similar DNA dual helices the correspond to each sister chromatid.
separation that homologs in meiosis I due to the fact that it produce 2 haploid (n) daughter cell from a solitary diploid (2n) parent cell. Separation of homologs outcomes in a reduction in chromosome number.
