Detailed Answers | Already Graded A+
Locus* - ✔✔Location of a gene on a chromosome
Sister Chromatids - ✔✔Replicated forms of a chromosome joined together by
the centromere and eventually separated during mitosis or meiosis II.
Non-sister chromatids - ✔✔Chromatids belonging to homologous chromosomes
Homologous Chromosomes - ✔✔Chromosomes that have the same sequence of
genes and the same structure
Non-Homologous Chromosomes - ✔✔Chromosomes that are not members of
the same pair
How does meiosis work? - ✔✔Meiosis creates gametes (eggs and sperm) with a
chromosome set (haploid or n) from parental cells with 2 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 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.
Meiosis I vs II - ✔✔Meiosis involves two sequential cellular divisions. In meiosis
I, homologous chromosomes pair and then separate. Thus, although the parent
cell is diploid (containing two chromosome sets, one maternal and one
paternal), each of the two daughter cells is haploid (containing only a single
chromosome set). In meiosis II, the sister chromatids separate. The four
daughter cells that result are haploid.
What happens at the end of meiosis I? - ✔✔At the end of meiosis I, homologous
chromosomes have separated into the daughter cells. The chromosomes that
align along the metaphase plate in meiosis II must consist of sister chromatids.
Prophase* - ✔✔First and longest phase of mitosis, during which the
chromosomes become visible and the centrioles separate and take up positions
on the opposite sides of the nucleus
Metaphase* - ✔✔Second phase of mitosis, during which the chromosomes line
up across the center of the cell
Anaphase* - ✔✔Phase of mitosis in which the chromosomes separate and move
to opposite ends of the cell
