Mitosis
Meiosis
Mitosis, Meiosis, or Both?
Mendel
Random
100

What is the fourth stage of mitosis called?

A. Prophase

B. Metaphase

C. Telophase

D. Anaphase

C. Telophase

100

What is the goal of meiosis

To create genetically different offspring

100

Are daughter cells genetically identical in meiosis? 

Yes or No

No, they are in mitosis though

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
100

Which gene is more likely to be passed on to offspring, a dominant allele or a recessive allele?

Ab 

Both have a 50./50 chance of being passed down. Phenotypically Dominant traits show up more often, technically. 

200

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

Cytokinesis

200
Meiosis is used for just one purpose in the human body the production of what?
Gametes
200

haploid cells

A. Mitosis

B. Meiosis

C. Both

 B. Meiosis

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

200

The parental gametes are aB x Ab. What are the possible parental and recombinant combinations

aB, ab, AB, Ab 

aB and Ab parental

ab and AB recombinant

300

How many complete sets of chromosomes are produced in mitosis?

46

300

How many daughter cells are produced in meiosis?

4 cells

300

Both Meiosis and Mitosis have centrosomes. WHat are the functions of centromsomes

Centrosomes duplicate and then move to opposite poles. The release of mitotic spindles that attach to the chromosomes centromere to split the homologs/sister chromatids
300

What is the difference between phenotype and genotype

Phenotype is the physical appearance and genotype is the genetic appearance 

300
Explain the difference between a sister chomatid and a homologs chromosome

Homologous chromosomes have same genes but different alleles (one from mom/ one from dad) seperate at meiosis 1 while a sister chromatid has identical genes and alleles (copies of one another), seperate at mitosis or meiosis 2

400

What happens in the third stage of mitosis?

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

400

In meiosis, how many chromosomes does each gamete contain?

23 chromosomes

400

 Involves all body cells.

A. Mitosis

B. Meiosis

C. Both

A. Mitosis

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. 

400

Give examples of codominance and incomplete dominance 

Codominace would be black and white spotted cow

incomplete would be a red and white flower making a pink flower

500
What is cytokinesis?
The division of the cytoplasm to form two new cells
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

500

Chromosomes condense.

A. Mitosis

B. Meiosis

C. Both

C. Both

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

500

If sister chromosomes were to be crossed, would there be genetic variation? Why or why not 

If a homologous chromosome were to be crossed, would there be genetic variation? Why, or why not? 


No bc sister chromosomes are identical copies of one another

Yes, bc homologous chromosomes have the same genes but not the same alleles.
