Meiosis
Genetic Variation
100
Centromeres uncouple at this stage
What is anaphase?
100
100 chromatids at metaphase would lead to how many chromosomes in a daughter cell
What is 50 chromosomes?
100
This important aspect of mitosis and meiosis is made of microtubules
What is mitosis spindle?
100
Meiosis makes these cells
What is gametes?
100
Crossing over occurs during this phase
What is prophase I?
200
You observe a plant cell with a cell plate forming and two new nuclei forming. What stage is this plant cell in?
What is telophase?
200
16 centromeres in a cell at anaphase will lead to this many chromosomes in a daughter cell?
What is 16 chromosomes?
200
Bacteria reproduce by which process instead of meiosis?
What is binary fission?
200
This process brings together a sperm and egg cell into a zygote
What is fertilization?
200
This creates new genetic combinations by making gametes with combinations of chromosomes that were not found in the parent generation
What is independent assortment?
300
Chromosomes are first visible after this stage
What is prophase?
300
16 centromeres in a cell at metaphase will lead to this many chromosomes in a daughter cell?
What is 8 chromosomes?
300
This structure occurs when an actin ring closes around the cell membrane during cytokinesis
What is cleave furrow?
300
After meiosis, a daughter cell has half the number of chromosomes compared to parent cell, but how much DNA?
What is half the amount as the parent?
300
This process occurs one to three times per chromosome per meiotic event.
What is crossing over?
400
Chromatids exist for an entire stage from which stage to which stage?
What is G2 to metaphase?
400
This is the shortest part of the cell cycle
What is mitosis?
400
A karyotype shows chromosomes in groups of two. What are these chromosomes called?
What is homologous pairs?
400
This type of chromosome are created during crossing over
What is recombinant chromosomes?
500
How many possible gametes are there for a cell with a diploid number of 14?
What is 128?
500
These chromosomes are the only pair that isn't exactly homologous, but acts that way
What is X & Y?
