Practice Meiosis Test
Plant clones can be produced by:
asexual reproduction.
The cell cycle of a typical somatic cell consists of __________ and M phase.
interphase
Refer to Figure 10-2. The process occurring at arrow 3 in the associated figure is:
meiosis
The correct number of chromosomes is maintained during sexual reproduction by:
meiosis, which reduces the chromosome number by half.
Sporophyte plants produce spores using:
meiosis.
Gametophyte plants produce gametes using:
mitosis
Which of the following are NOT produced by meiosis?
zygotes.
Refer to Figure 10-1. Which of the following combinations of letters accurately represents two sister chromatids?
A and C
Refer to Figure 10-1. Which of the following combinations of letters accurately represents two homologous chromatids?
A and D
A diploid cell contains 6 chromosomes. After meiosis I, each of the cells contain:
A mixture of maternal and paternal chromosomes totaling 6.
During which of the following stages of meiosis do the sister chromatids separate?
anaphase II
An animal with a diploid number of 36 chromosomes will have __________ chromosomes in its gametes and __________ chromosomes in its somatic cells.
18;36
In a human cell at prophase I, there are __________ tetrads.
23
Daughter chromosomes migrate towards the poles:
Anaphase II
Which occurs in Meiosis I and but not in meiosis II?
Crossing over of homologous chromosomes occurs.
A zygote contains the __________ complement of chromosomes.
Diploid
Meiosis produces
Genetically .Variable cells
In sexually reproducing organisms, the source of chromosomes in the offspring is:
Half from the father and half from the mother.
Meiosis results in the production of:-
Haploid cells with unpaired chromosomes.
Crossing over occurs during:
Prophase I
During prophase I, each chiasma represents:
a site of crossing-over.
A maternal homologue and a paternal homologue synapse to form:
a tetrad.
If meiosis did not occur in sexually reproducing organisms, then:
chromosome number would double in each generation.
The sources of genetic variation during meiosis are:
crossing-over and the random assortment of maternal and paternal chromosomes.
A zygote contains the __________ complement of chromosomes.
diploid
Most human somatic cells are:
diploid
Which of the following events does not occur in prophase II?
formation of chiasmata
Refer to Figure 10-2. The chromosome complement of item 6 in the life cycle is:
haploid
What evolutionary advantage is provided by sexual reproduction?
increased genetic diversity
The formation of female gametes is termed:
oogenesis
Homologous chromosomes undergo synapsis during:
prophase I.
Which of the following events does not occur during meiosis I?
separation of sister chromatids
During prophase I of meiosis, homologous chromosomes lie side by side. This phenomeon is known as:
tetrad formation.
