Question

6. During which stage(s) of meiosis do you expect to find tetrads?

A. Prophase I only
B. Prophase I and metaphase I
C. Prophase I, metaphase I, and anaphase I
D. Prophase I and prophase II

7. The stages of meiosis where independent assortment occurs and crossing over

begins, respectively, are
A. Metaphase I and II and prophase I and II
B. Metaphase I and prophase II
C. Metaphase I and prophase I
D. Metaphase II and prophase I

10. In an organism with a diploid number of 16, how many chromatids are present in each
of the following phases:
Mitotic metaphase=
Meiotic metaphase I=
Meiotic metaphase II=
Meiotic telophase II=

30. Oogenesis involves germ cells in the ovary undergoing meiosis to produce a

functional ovum at the end of the process.
Which of the following cells is penetrated by a sperm cell during the process
of fertilization?
A. Oogonia
B. Secondary oocyte
C. Primary oocyte
D. Ovum

34. Why is parthenogenesis in bees considered to be a form of

asexual reproduction?
A. The formation of the original haploid cell was achieved using binary fission.
B. The haploid male bees were made through the process of meiosis, so they
are identical to the parent egg cell.
C. Although genetic material is transferred from one cell to another using
conjugation, the resulting cells will be identical to each other.
D. The male drone is made from a haploid egg. Fertilization is not part of the
process to make a male drone.

36. Since the seedless bananas are triploid ] g 3n , and do not produce viable seeds
for reproduction. To grow more seedless banana plants, farmers take a side
shoot and replant it.
This type of asexual reproduction is called
A. Binary fission
B. Parthenogenesis
C. Fragmentation
D. Budding

Answer 1

Ans 6. Tetrad is form in the Prophase I of the meiosis. Tetrads are a group of two homologous chromosomes that come together to undergo the crossing over event in meiosis.

So right answer is (A) Prophase I only

Ans 7. Crossing over occurs during prophase I of meiosis and ndependent assortment occurs during the metaphase I

So the right answer is Metaphase I and Prophase I

Ans 10. .In a diploid organism with a ploidy number of 16, the number of chromatids in each of the following stages will be:

Mitotic Metaphase: 32

Meiotic Metaphase I: 32

Meiotic Metaphase II: 32

Meiotic Telophase II: 16

Ans 30. (D) Ovum

Ovum is penetrated by a sperm cell during the process

of fertilization.

Ans 31 Seedless fruits in the banana are produced through parthenocarpy which is a type of parthenogenesis. The female flowers of the inflorescence present on the true stem mature and develop into fruit without fertilization of gametes while the male flowers produce pollen which may be sterile.

So the right answer is (B). Parthenogenesis
