Mitosis

100

What is the fourth stage of mitosis called?

A. Prophase

B. Metaphase

C. Telophase

D. Anaphase

C. Telophase

200

What is the stage after mitosis called? (Not part of PMAT)

Cytokinesis

300

How many complete sets of chromosomes are produced in mitosis?

46

400

What happens in the third stage of mitosis?

In this stage the sister chromatids separate into individual chromosomes and are pulled apart.

500

What is cytokinesis?

The division of the cytoplasm to form two new cells

Meiosis

100

What is the goal of meiosis

To create genetically different offspring

200

Meiosis is used for just one purpose in the human body the production of what?

Gametes

300

How many daughter cells are produced in meiosis?

4 cells

400

In meiosis, how many chromosomes does each gamete contain?

23 chromosomes

500

 What are the 8 phases of meiosis called?

8 phases: prophase I and II, metaphase I and II, anaphase I and II, telophase I and II

Mitosis, Meiosis, or Both?

100

Are daughter cells genetically identical in meiosis? 

Yes or No

No, they are in mitosis though

200

Ends up with 4 daughter cells.

A. Mitosis

B. Meiosis

C. Both

 B. Meiosis

300

 Original parent cell divides twice.

A. Mitosis

B. Meiosis

C. Both

 B. Meiosis

400

 Involves all body cells.

A. Mitosis

B. Meiosis

C. Both

A. Mitosis

500

Chromosomes condense.

A. Mitosis

B. Meiosis

C. Both

C. Both

Mendel

100

Give 2 reasons why pea plants are great for gentic experiments

• Have both. Male and female gametes
• Create lots of offspring quickly
• Lots of either-or traits (characters’ phenotypic traits)
• A variety of pea plants were true-breeding (all offspring have same phenotype as parents)
• Disproved blending

200

If you cross a true breeding dominant flower with a true breeding recessive flower, what will the geneotypes be of the offspring? 

do punnett square

300

What is the difference between phenotype and genotype

Phenotype is the physical appearance and genotype is the genetic appearance 

400

Mendel crossed pea plants that differed in two traits, seed color and seed shape. He observed a 9:3:3:1 ratio in the offspring. What principle does this test prove?

It states that alleles for different genes separate independently during gamete formation. How the chromosomes line up during meiosis 1. 

500

In pea plants,

• Seed shape: Round (R) is dominant to wrinkled (r)

• Seed color: Yellow (Y) is dominant to green (y)

A plant that is heterozygous for both traits (RrYy) is crossed with another plant that is also heterozygous for both traits (RrYy). Find the genotypes of the offspring

Do dihybrid cross
