Cell Division 1
The genetic variation that occurs in sexually reproducing organisms is the result of these three processes.
What is crossing-over of homologous chromosomes, independent assortment, and random fertilization?
This type of asexual reproduction occurs when a parent organisms breaks into fragments or pieces and each fragment develops into a new organism.
What is fragmentation?
Mutation of cell cycle checkpoints results in unregulated cell growth, which is known as this.
What is cancer?
This part of the cell cycle actually includes both mitosis and cytokinesis.
What is Mitotic phase or M phase?
This type of reproduction involves only 1 parent and the result is a clone of the parent.
What is asexual reproduction?
This part of the cell cycle preps the cell for DNA synthesis.
What is G1 Phase?
This part of the cell cycle is when the cell copies its DNA.
What is S Phase?
The exchange of genetic material within a pair or homologous chromosomes that create unique combinations of alleles/genes is known as this.
What is recombination or crossing over?
The process where cells replace other cells and does NOT occur in germ line cells is this.
What is mitosis?
The result of meiosis, these cells unite to form offspring.
What are gametes?
A pair of chromosomes in a cell that contain the same genes in the same order are known as this.
What are homologous chromosomes?
Gametes have this ploidy.
What is haploid?
This is how organisms grow and repair themselves.
What is cell division?
The random assorting of rearranged homologous chromosomes following crossing over into separate daughter cells is known as this.
What is independent assortment?
The G1, S, and G2 phases together are collectively known as this.
What is Interphase?
This is the process by which organisms give rise to offspring.
What is reproduction?
This type of asexual reproduction is when a parent cell splits into two identical cells of the same size.
What is binary fission?
What is a tetrad?
A fertilized cell is called this.
What is a zygote?
This is a molecule of DNA.
What is a chromosome?
This part of the cell cycle is when the cell makes its final preparations to divide.
What is G2 Phase?
The process when random gametes unite is called this.
What is fertilization?
A repeating series of events that include growth, DNA synthesis, and cell division is called this.
What is the cell cycle?
Zygotes have this ploidy.
What is diploid?
This type of asexual reproduction occurs when a bubble like appendage appears and develops into a new organism.
What is budding?
