21 Questions
Which type of reproduction involves the parent passing down all of its DNA to the offspring?
Asexual reproduction
What is the term for a pair of chromosomes that have genes for the same characteristics at the same loci?
Homologous chromosomes
If a sexually reproducing organism has a chromosome number of 2N = 18, how many chromosomes are in each of its sex cells?
9
What type of cell division results in cells with half the number of chromosomes as the original cell?
Meiosis
What is the term for a cell that has one of each kind of chromosome?
Haploid
During which stage of meiosis are tetrads formed?
Prophase I
What is the advantage of sexual reproduction?
Increased genetic diversity
During which stage of meiosis do tetrads line up at the center of the cell?
Metaphase I
What term is used to describe the sex cells?
Gametes
During anaphase I, what is pulled apart?
Homologous chromosomes
What is the symbol for diploid?
2N
What is the process called when genes exchange between segments of homologous chromosomes during meiosis?
Crossing over
What happens to the nuclear envelope during prophase I of meiosis?
It breaks down
During which stage of meiosis I do the microtubules from opposite spindle poles capture the sister chromatids of each chromosome?
Metaphase I
During which stage of meiosis II is there no formal interphase?
Meiosis II as a whole
What is the end result of the meiosis process in terms of chromosome number?
Haploid
What happens to the sister chromatids of each chromosome during anaphase I?
They are pulled towards opposite poles of the cell by the microtubules.
What occurs during telophase I?
Nuclear membranes form around each set of chromosomes, and the chromosomes decondense.
What happens during prophase II?
The chromosomes condense, and the nuclear envelope breaks down if needed.
What is the result of anaphase II?
Each daughter cell receives one chromatid from each chromatid pair.
What is the final product of meiosis II?
Four haploid cells in which each chromosome has just one chromatid.
