What phase of meiosis is shown by the image?
Metaphase I
Metaphase II
Prophase I
Telophase III
How many chromosomes would a cell have during metaphase I of meiosis if it has 12 chromosomes during interphase?
6
12
24
1
What is the next step for the chromosomes illustrated above?
They will experience replication.
They will experience fertilization.
Their number per cell will be halved.
They will divide into sister chromatids.
Which is not a characteristic of homologous chromosomes?
Homologous chromosomes have the same length.
Homologous chromosomes have the same centromere position.
Homologous chromosomes have the exact same type of allele at the same location.
Homologous chromosomes pair up during meiosis I.
If a black hamster (Bb) were crossed with a white hamster (bb) what would be the resulting phenotypic ratio?
0:1 black to white
1:0 black to white
1:1 black to white
3:1 black to white
In garden peas, purple flowers (P) are dominant to white (p) flowers, and tall plants (T) are dominant to short plants (t). If a purple tall plant (PpTt) is crossed with a white short plant (pptt), what is the resulting phenotypic ratio?
1:1:1:1 purple tall to purple short to white tall to white short
3:2 purple tall to purple short.
9:3:3:1 purple tall to purple short to white tall to white short.
All purple tall
The unusual cat shown was crossed with a cat with noncurled ears. All the kittens born from that cross had noncurled ears. Later, when these offspring were crossed with each other, the phenotypic ratio was 3:1 non-curled to curled ears. What conclusions can be made about the inheritance of curled ears?
Curled ears are a result of crossing over.
It is a dominant trait.
It is a recessive trait.
More crosses need to be done to determine how the trait is inherited.
Which of the following does not contribute to genetic variation?
Chromosome number
Crossing Over
Meiosis
Random partnerships for mating
Which concept is considered an exception to Mendel’s law of independent assortment?
Crossing over
Genetic Linkage
Polyploidy
Law of segregation
A housefly, shown in the photo above, has six pairs of chromosomes. If two houseflies are crossed, how many possible types of fertilized eggs could result from the random lining up of the pairs?
2^8 = 256
2^10 = 1024
2^12 = 4096
2^6 = 64
For the housefly with its six pairs of chromosomes, how many possible combinations of gametes can be produced by the random lining up of pairs in meiosis?
2^8 = 256
2^10 = 1024
2^12 = 4096
2^6 = 64
Which process divides a cell’s nucleus and nuclear material?
mitosis
cytokinesis
interphase
cell cycle
In a cell undergoing meiosis, during which stage do the sister chromatids separate from each other?
Anaphase I
Anaphase II
Telophase I
Telophase II
Reproductive cells, which pass on genetic traits from the parents to the child, are produced by the process of _________________.
mitosis
meiosis
cytosis
cytokinesis
