Question 1: What is a sister chromatid?

Answer:

Each half of a replicated chromosome is a sister chromatid.

Question 2: What is uncoiled, stringy DNA called?

Answer:

It is called chromatin.

Question 3: What is cytokinesis?

Answer:

The division of the cytoplasm to make two new cells is cytokinesis.

Question 4: What happens in prophase one?

Answer:

In prophase one, the nucleus disintegrates, and chromoses condense and become visible. Homologous chromosomes pair up to make a tetrad.

Question 5: What are different forms of genes called?

Answer:

Different forms of genes are called alleles.

Question 6: What are the phases of meiosis two?

Answer:

Meiosis two includes prophase two, metaphase two, anaphase two, and telophase two.

Question 7: How many pieces of chromatin does a human diploid cell have?

Answer:

Human diploid cells have 46 pieces of chromatin.

Question 8: What are diploid cells?

Answer:

Diploid cells are cells that have pairs of chromosomes.

Question 9: Why are the two new cells that form from meiosis one haploid cells?

Answer:

They are haploid cells because they have half the chromosome as the original cell.

Question 10: What is the definition of sexual reproduction?

Answer:

Sexual reproduction is when two organisms combine genetic information to create a baby.

Question 11: What alleles are there in Snurfles?

Answer:

There is an allele for green fur, and there is an allele for yellow fur. G is for yellow fur, and g is for green fur.

Question 12: What are gametes?

Answer:

Gametes are sperm and egg cells.

Question 13: What do you have at the beginning of meiosis one?

Answer:

At the start, you have one diploid cell.

Question 14: How many divisions are in meiosis?

Answer:

There are two division in meiosis.Question 15: When do homologous chromosomes split up and move to opposite ends of the cell?

Answer:

This occurs in anaphase one.

Question 16: How would you define homologous chromosomes?

Answer:

Pairs of chromosomes that have genes for the same traits arranged in the same way are homologous chromosomes.

Question 17: What is a zygote?

Answer:

The new cell that is created by fertilization is a zygote.

Question 18: What are the phases of meiosis one?

Answer:

Meiosis one includes prophase one, metaphase one, anaphase one, and telophase one.

Question 19: What occurs during metaphase two?

Answer:

The chromosomes line up single file down the middle of the cell.

Question 20: What is the middle of the cell called?

Answer:

The middle of the cell is the equator.

Question 21: What occurs during telophase two?

Answer:

Four haploid daughter cells are being formed in telophase two. The chromosome uncoil to form chromatin. Each newly formed cell develops a nucleus around its chromosomes.

Question 22: What does DNA have that determines traits in organisms?

Answer:

DNA has genes that determine traits in organisms.

Question 23: Why must meiosis two take place?

Answer:

Meiosis two must take place because the cells from meiosis one have too much DNA.

Question 24: What happens in anaphase two?

Answer:

In anaphase two, sister chromatids split up.

Question 25: What are haploid cells?

Answer:

Haploid cells, also know as sex cells, have half the amount of chromosomes body cells have in that organism. In other words, a haploid cell has one chromosome from every pair.

Question 26: What occurs during interphase?

Answer:

DNA (chromatin) replicates itself.

Question 27: What occurs in metaphase one?

Answer:

The tetrad line up in the middle of the cell during metaphase one.

Question 28: What happens during telophase one?

Answer:

Two independent cells begin to form in telophase one.
