Multiple Choice

In this type of reproduction, a sperm & egg are required.

• Budding

• Asexual Reproduction

• Binary Fission

• Sexual Reproduction

Multiple Choice

Prokaryotes (Bacteria) undergo cell division that results in reproduction in a process known as?

• Budding

• Binary Fission

• Regeneration

• Duplication

Multiple Choice

One advantage to asexual reproduction is

• You don't need to find a mate

• There's a lot of genetic variety

• It takes longer

• Fewer Offspring are produced

Multiple Choice

You are looking at the offspring of an organism and notice that it has the exact copy of its parents genes. What type of reproduction has occurred?

• Asexual Reproduction

• Sexual Reproduction

• Binary Reproduction

• None of these!

Multiple Choice

What critical step must occur during Interphase I?

• DNA must be replicated prior to meiosis

• RNA must be transcribed prior to meiosis

• Meiosis I must be completed

• Gametes must form in the gonads

Multiple Choice

Another name for Sperm & Egg cells is?

• Mesocytes

• Cellocytes

• Gametes

• Prokaryotes

Multiple Choice

2N is the symbol used to represent an organism that is?

• Diploid

• Haploid

• Tetroid

• Duplexed

Multiple Choice

How many viable sex cells do males produce during meiosis?

• 2

• 4

• 6

• 1

Multiple Choice

How many viable sex cells do females produce during meiosis?

• 1 viable & 3 polar bodies

• 2 viable & 0 polar bodies

• 4 viable

• 3 viable & 1 polar body

Multiple Choice

Pair of chromosomes (maternal and paternal) that are similar in shape and size.

• Homologous

• Chromatid

• Locus

• Synapsis

Multiple Choice

A pair of homologous chromosomes or 4 chromatids are known as?

• Locus

• Tetrad

• Autosome

• Gametes

Multiple Choice

Homologous chromosomes come together to form a tetrad, also known as?

• Locus

• Gametes

• Diploid

• Synapsis

Multiple Choice

This process happens when segments of nonsister chromatids break and reattach to the other chromatid in a tetrad.

• Meiosis

• Diploid to Haploid

• Reduction Division

• Crossing Over

Multiple Choice

The site of crossing over between a pair of homologous chromosomes.

Multiple Choice

Meiosis I stage where;

Diploid has turned into Haploid as the parent cell prepares to undergo cytokinesis.

• Metaphase I

• Anaphase II

Multiple Choice

Part of Meiosis where;

There is no Interphase II

There is no DNA replication

Starts with 2 Haploid Cells

• Meiosis I

• Anaphase I

Multiple Choice

Stage of meiosis where sister chromatids separate.
