Pick me! Pick Me!
100
Synapsis and crossing over occur in this phase
What is Prophase 1
100
2 sister chromatids are held together by
What is a centromere
100
Any deviation from the exact number of chromosomes is known as
What is Aneupoloidy
100
When does oogenesis begin?
What is approximately 20 weeks in utero (inside the mom's womb)
100
When chromosomes do not separate properly, this can lead to chromosomal anomalies this is called
What is Nondisjunction
200
2 cells are created with 46 chromosomes
What is Telophase 1
200
Fibers that extend from centromsome to centrosome
What is polar fibers
200
What is a Genetically Modified Organism
What is an organism that DNA has been manipulated in some way
200
The Head of the sperm is known as
What is an Acrosome
200
What is our genetic code that makes us unique?
What is 4 nitrogen bases (Adenine-Thymine and Cytosine and Guanine)
300
Independent Assortment occurs during this phase
What is Metaphase 1
300
The notch located on a centromere where the fibers connect to
What is a kinectochore
300
An alternative name for a gene ?
What is an allele
300
How long does the process of Spermatogenesis take?
What is about 72 days
300
What is the Human Genome Project?
What is --it is International effort that helps map out what chromosomes control what traits.
400
The centromere splits in meiosis during which phase
What is anaphase 2
400
Chromosomes that have the same genes at the same locations are known as
What is Homologous Chromosomes
400
How is oogenesis more complex than spermatogenesis?
What is oogenesis starts in utero, stops and pauses in Prophase 1, then picks up again at puberty and stops at menopause. Also, result is one big functional egg and 2-3 polar bodies that are non functional. Whereas, spermatogenesis starts at puberty- continues until death and creates 4 haploid symmetrical cells.
400
Where does oogenesis and spermatogenesis take place?
What is Oogenesis-ovary/ Spermatogenesis-testes
400
What is a transgenic organism?
What is an organism that has another species DNA in its own Genome
500
The tetrad splits and moves to opposite poles during which phase
What is Anaphase 1
500
4 part question: When the homologous chromosomes seek out and find each other? Where the homologous chromosomes touch? What happens at the location where they touch
What is Synapsis, Chiasma, Crossing over
500
In oogenesis, the cell is suspended in this phase until puberty? What is the technical name of the cell when it is suspended?
What is Prophase 1 and the cell is called a Primary Oocyte
500
Chromosomes did not separate properly. The baby is a female with 45 chromosomes, which disease is this?
What is Turners syndrome
500
List 4 things that cause Genetic diversity
What is Crossing over, independent assortment, Random sexual reproduction, mutations
