Module 1.2 Meiosis First Div

Question 1

During the ___ stage, the microtubules of the spindle are attached to the ___ at the ___ of the homologous chromosomes of each tetrad, aligning chromosomes at the equator.

Centromere is directed towards the opposite poles. The repulsive forces between the homologous chromosomes increase greatly and the chromosomes become ready to separate

Answer 1

Metaphase I

kinetochores
centromeres

Question 2

During the ___ stage, homologues are freed from each other due to the shortening of chromosomal fibers or microtubules.

Chromosomes with less terminal chiasmata separate more frequently.

The two chromatids of a chromosome do not resemble each other genetically

Answer 2

Anaphase I

Question 3

During the ___ stage, a haploid set of chromosomes arrive at each pole.

Nuclei are then reassembled.

___ forms near the nuclear envelope around the chromosomes and the chromosomes become uncoiled.

The ___ reappears and thus two daughter ___ are formed.

Karyokinesis and cytokinesis occur and two haploid cells are formed.

Short interphase occurs.

Answer 3

Telophase I

endoplasmic reticulum

Nucleolus
Nuclei
