Gametes, such as eggs and sperm, are haploid reproductive cells that fuse during fertilization in sexual life cycles.
You are watching: Which statement is false concerning gametes produced by meiosis?
Which statement correctly describes a key difference between cells entering prophase of mitosis versus prophase I of meiosis?
For cells entering mitosis, homologous chromosomes function independently; for cells entering meiosis, homologous chromosomes pair up.
What effect do meiosis and fertilization have on the ploidy level of cells produced by each process?
Meiosis decreases the ploidy level from 2n to n; fertilization increases the ploidy level from n to 2n.
Meiosis creates gametes (eggs and sperm) with only a single chromosome set (haploid or n) from parental cells with two chromosome sets (diploid or 2n). During fertilization, the haploid sperm (n) and egg (n) fuse, producing a diploid zygote (2n). The cells of the zygote then divide by mitosis (which does not change the ploidy level) to produce an adult organism (still 2n) of the next generation.In sexual life cycles, meiosis and fertilization keep the number of chromosomes constant from generation to generation.
Which statement is correct concerning the relationship between chromosomes and chromatids?A replicated chromosome contains a single chromatid. An unreplicated chromosome contains a single chromatid. An unreplicated chromosome contains two sister chromatids. A replicated chromosome contains two sister chromatids.
A replicated chromosome contains two sister chromatids.A replicated chromosome contains two identical DNA double helices that correspond to each sister chromatid.
separation of homologs in meiosis I because it produces 2 haploid (n) daughter cells from a single diploid (2n) parent cell. Separation of homologs results in a reduction in chromosome number.
A diploid organism whose somatic (nonsex) cells each contain 32 chromosomes produces gametes containing _____ chromosomes.
