Studied by 27 peopleIs binary fission sexual or asexual reproduction?
Asexual
What type of reproduction creates 4 daughter cells?
Sexual reproduction
When homologous chromosomes are being separated, what phase is that?
Anaphase I
When does crossing over occur?
Prophase I
What process that involves egg and sperm eventually will happen to create a diploid organism?
Fertilization
If diploid is a full set of chromosomes, what is haploid?
Half the chromosomes/one set of chromosomes
When homologous pairs are separated, and the cell membrane is beginning to pinch together, what phase is that?
Telophase I
What type of graph do you make for comparing two or more things?
Bar graph
When homologous chromosomes swap pieces of DNA, what is that called?
Crossing over
When there are two genetically identical daughter cells, is that sexual or asexual reproduction?
Asexual reproduction
What kind of graph do you make for change over time?
Line graph
What are two things that asexual and sexual reproduction have in common?
Reproduce new offspring, offspring have full set of DNA,
When offspring are genetically identical, is that sexual or asexual reproduction?
Asexual reproduction
When sister chromatids are being separated, and there are two cells present, what phase is that?
Anaphase II
Are sperm and egg haploid or diploid?
Haploid
What is a picture of all the chromosomes in a cell called?
Karyotype
If a karyotype has sex chromosomes, is that sexual or asexual reproduction?
Sexual reproduction
How many cells are made at the end of meiosis?
Four
What is the scientific term for sex cells?
Gametes
If the haploid number of chromosomes is 14, what is the diploid number?
28
What is the entire purpose of meiosis?
Create genetically different cells/offspring
What is a pair of replicated, similar chromosomes from mom and dad called?
Homologous pair
What is the 23rd pair of chromosomes called?
Sex chromosomes
Where does your reasoning section for your CER come from?
Background information
Would asexual reproduction, sexual reproduction, or both have offspring with a full set of DNA?
Both
How many chromosomes do egg and sperm cells have at the end of meiosis?
23
What two things go into a graph title?
Independent and dependent variables
How many cells are present at the end of one round of asexual reproduction?
Two
Does meiosis create genetically different or genetically identical offspring?
Different
What are the first 22 pairs of chromosomes of humans called?
Autosomes
Your claim for your CER answers what?
The scientific question
What is the name of asexual reproduction in bacteria?
Binary fission
Which would better survive a viral attack- an asexually reproducing population or a sexually reproducing population?
Sexual
What is a fertilized egg called?
Zygote
Asexual and sexual reproduction both use DNA to create new life, true or false?
True
When chromosomes in meiosis do not correctly separate- what is that called?
Nondisjunction
What is it called during Metaphase I when homologous chromosomes line up randomly?
Independent assortment
What phase is this?
Anaphase 1
-homologous pairs are being pulled apart
What phase is this?
Anaphase II
-sister chromatids are being pulled apart
What phase is this?
Cytokinesis I
-two cells are finally separated
-nucleus is reforming
What phase is this?
Interphase
-DNA is in chromatin form
-The nucleus is fully intact
What phase is this?
Metaphase I
-Homologous pairs are lined up in the middle of the cell
What phase is this?
Metaphase II
-Sister chromatids are lined up in the middle of the cell
What phase is this?
Prophase I
-DNA is condensing to chromosomes
-Crossing over happens
-Spindle fibers are forming
-Nucleus is going away
What phase is this?
Prophase II
-Nucleus is going away
-DNA is condensing to chromosomes
What phase is this?
Telophase I
-Cells are starting to split
-Can see a cleavage furrow
What phase is this?
Telophase II
-Cells are starting to split
-Can see a cleavage furrow
