Question 5
5.

A cell undergoes Meiosis I with no crossing over between homologous chromosomes. Which outcome is most likely?

Question 6
6.

Name the event wherein the paternal and maternal chromosomes change their material or exchange the parts with each other in cell division. Which phase does it happen?

Question 7
7.

Drag and drop the description to the category that it belongs to.

  • Homologous chromosomes align at the equator.
  • Centrioles move towards the poles.
  • Four daughter cells with haploid number of chromosomes is formed.
  • Followed by Cytokinesis
  • The sister chromatids of recombinant chromosomes move apart
  • Crossing over occurs here.
  • Nucleolus and nuclear membrane disappear.
  • Two daughter cells with haploid number of chromosomes is formed.
  • Meiosis-I
  • Meiosis-II
  • Both Meiosis-I and Meiosis-II
Question 8
8.

A student claims that crossing over is unnecessary because independent assortment alone creates genetic diversity. Which statement best evaluates this claim?

Anaphase-II
Metaphase-I
Crossing Over

Question 11
11.

Haploid gametes have ......# of chromosomes whereas Diploid cells have .....# of chromosomes

Question 12

14.

One difference between Autosomes and sex chromosomes humans is-

Question 15
15.

How does independent assortment affect genetic variation?

Question 16
16.

What purpose does a karyotype serve in genetics?

Question 17
17.

Which statements correctly describe chromosomes during metaphase II? (Check all that apply)

Question 18
18.

If nondisjunction occurs during anaphase II of one daughter cell, which outcomes are possible in the resulting gametes? (Check all that apply)

Question 19
19.

What are the similarities between meiosis I and meiosis II?

Question 20
20.

Rearrange the events in Meiosis-I in the correct order

  1. The Homologous pairs of chromosomes line up at the equator/middle.
  2. The homologous chromosomes exchange their parts.
  3. The recombinant chromosomes move apart.
  4. The two haploid daughter cells completely divides and is ready to go next.
  5. Synapsis occurs.
  6. The nucleolus and the nuclear membrane reappears.
Question 21
21.
