Asexual vs. Sexual Reproduction
Which type of reproduction involves only one organism as a parent?
Asexual
During what stage of the cell cycle is the cell's DNA replicated?
S (Synthesis) Phase
Prophase, Metaphase, Anaphase, Telephase
The diploid number of chromosomes in a human skill cell is 46. How many chromosomes are in a human egg cell?
23
What process is directly involved in the formation of gamete cells?
Meiosis
What is budding? What organisms use budding to reproduce?
A type of asexual reproduction where the parent divides into two uneven parts. Yeast do this.
Cell growth occurs in
G1
During which part of the cell cycle goes Mitosis happen?
M Phase
Meiosis always produces what type of gametes?
haploid
A fish contains 28 chromosomes in its' body cells. When starfish reproduce, the zygote will contain chromosomes.
28
more genetic diversity
G2 Phase
Chromosomes form from chromatin, spindle fibers form, centrioles move to opposite poles, and the nuclear envelope disappears during which phase of mitosis?
Prophase
What is the benefit of crossing over?
It helps to ensure greater genetic variation in the new cells.
Chromosomes are held together at a point called the
Centromere
What kind of replication happens in prokaryotic cells?
Binary Fission
What are the 2 different parts of the cell cycle?
M Phase and Interphase
Which Phase is described here?
The linear orientation down the center of the cell aligns the chromosomes, ensuring that the chromatids of each chromosome are positioned for separation to opposite ends of the cell.
Metaphase
What happens during crossing over in meiosis?
exchange of genetic material between homologous chromosomes
The number of chromosomes in a cell is reduced to half during __________, but remains the same during___________
Meiosis; Mitosis
What is being described here?
At which point does the cell undergo cytokinesis?
AFTER M phase (The end of the cell cycle)
How many daughter cells are produced in Mitosis?
Two
4
What is represented by 2n
diploid cells
