Biology I-Unit 5 Reproduction

Is 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
