Mitosis
In what phase do the chromosomes line up in the middle of the cell?
Metaphase
In meiosis, what happens to the number of chromosomes?
They are cut in half
In what phase does crossing over occur?
Prophase
Give one reason why asexual reproduction is important.
How many daughter cells does mitosis result in? Are they diploid or haploid?
2, diploid
A cell with 40 chromosomes undergoes mitosis. How many chromosomes do the daughter cells have?
40
How many daughter cells does meiosis result in? Are they diploid or haploid?
4, haploid
Interphase, S
Give me 2 things that occur during prophase.
Spindle fibers start to form, chromosomes condense, nuclear envelope disappears
If a haploid cell has 27 chromosomes, how many chromosomes would the diploid cell have?
54
How is prophase I in meiosis different from prophase in mitosis?
Homologous chromosomes pair up instead of sister chromatids, crossing over occurs
What is another word for reproducing asexually?
Mitosis
Give all the phases of interphase and mitosis.
G1, S, G2, prophase, metaphase, anaphase, telophase, cytokinesis
A cell with a diploid number of 38 undergoes meiosis. How many chromosomes do the gametes end up with?
19
In what phases of meiosis do you have homologous chromosomes paired up?
Prophase I, metaphase I
In terms of DNA, what is a gene?
A segment of DNA that codes for a protein.
