question
A hypothetical cell has a chromosome number of 2n = 16. Which of the following statements is TRUE?
answer
The diploid cells from this species have 8 homologous pairs of chromosomes.
question
germ cells are ________ cells that go through the process of meiosis to form ______________________
answer
diploid, haploid gametes
question
Metaphase 1
answer
homologous pairs of chromosomes line up on the metaphase plate
question
Anaphase 1
answer
homologous pairs are pulled apart, they move toward poles of cell
question
Telophase 1
answer
cytokinesis occurs and two new daughter cells are formed
question
What does meiosis 1 do to the # of chromosomes?
answer
halves them
question
After telophase I of meiosis, the chromosomal makeup of each daughter cell is:
answer
haploid, and the chromosomes are each composed of two chromatids.
question
In which stage of meiosis are sister chromatids separated?
answer
Anaphase II
question
where does nondisjunction occur
answer
chromosomes are not serrated correctly during metaphase I or II, resulting in gametes with too few or too many chromosomes
question
what is nondisjunction
answer
The unequal separation of homologous chromosomes results in cells with more or less chromosomes than normal.
question
Mitosis results in ______ cells and meiosis results in _______ cells.
answer
diploid, haploid
question
Homologous chromosomes separate and are pulled to opposite sides of the cell during what stage of cell division? (Read each option carefully.)
