What are homologous chromosomes? Contrast the genetic makeup of sister chromatids with nonsister chromatids.

Sister chromatids are found in

Sister chromatids are joined at

Identify the meiotic stage in which the homologous chromosomes separate while the sister chromatids remain associated at their centrometres. Or In which stage of meiosis homologous chromosomes are segregated

The homologous chromosomes separate, while sister chromatids remain associated at their centromeres during

Sister chromatids of a chromosome have :

Parental chromosome produce two identical sister chromatids during

Match the above figures (a, b, c) with their events given below :- (I) Nucleolus disappear (II) Formation of tetrad of cell (III) Homologous chromosomes separate (IV) Microtubules attached to the kinetochore of sister chromatids (V) Separation of sister chromatids (VI) Bivalent chromosomes align on theequatorial plate

Failure of separation of sister chromatids us

A : Anaphase-I is actual phase of reduction in number of chromosomes. R : Homologous chromosomes move to the opposite poles with both their chromatids.

The figure given below represents the stage of cell division. Read the following statements. (i) Nucleolus, Golgi complex and ER reform. (ii) Chromatids move to the opposite pole. (iii) The activity of the recombinase enzyme. (iv) Homologous chromosomes separate while sister chromatids associated at their centromere. (v ) Initiation of the assembly of the mitotic spindle. How many of the above statements is not true with respect to the above figure
