What is a genetic disorder?

an illness caused by genetic changes to a persons DNA

100

What is an allele?

one of two or more forms of a gene

100

These are the stages of mitosis.

prophase, metaphase, anaphase, telophase

100
Brown eyes are dominant (B) while blue eyes are recessive (b). This is the genotype for Jill who is heterozygous for brown eyes.
What is Bb?
100
This molecule is involved in the transmission of information from one generation to the next?
What is DNA?
200

Name three ways genetic changes can occur?

change to a single gene

increase or decrease in chromosomes

multiple changes to one or more genes combined with environmental factors

200

compare phenotype to genotype

genotype is the specific combination of alleles

phenotype is the physical description of an organisms trait.

200
This is the term that describes a cell with only one complete set of chromosomes.
What is haploid?
200
Brown eyes are dominant (B) while blue eyes are recessive (b). This is the phenotype for James who is homozygous recessive.
What is blue eyes?
200
These are the three parts of a nucleotide.
phosphate, sugar, base

What is cancer? What are the causes?

is the uncontrolled growth and divisions of cells-a failure in the regulation of the cell cycle


Due to a mutation in the segments of DNA that control cell cycle.

300

Homozygous compared to heterozygous

homozygous means two of the same alleles

heterozygous two diiferent alleles for a particular trait

300

Are gametes haploid or diploid?

haploid

300
Red flower and white flower make a pink flower. This is an example of what?
What is codominance?
300

The first mammal cloned was....

Dolly the sheep

400

Nondisjunction Define:

When it can occur

and the results

an error that occurs during meiosis that results in too few or too many chromosomes

Anaphase I or II

Abnormal gametes 2 gamets have too many 2 gamets havve 2 few

or 2 normal gametes and 1 gamet too many and 1 gamete too few

400

What is a pedigree?

a visual representation of how a trait is inherited in different generations

400

at what stage in meiosis do homologous chromosomes pair  up along the middle of the cell?

Metaphase I

400
Jill is heterozygous for brown eyes and James is homozygous recessive for blue eyes. This percent age of their children could be expected to have brown eyes.
What is 50%
400

How many mothers did dolly the sheep have?

3

donor egg

donor DNA

surrogate mom

500

Briefly describe one DNA technology and give an example of how it is used

Reproductive technology

genetic testing

Designer babies

Saviour siblings

cloning

GMO

Gene therapy

500

Why does the expression of a trait determined by a recessive allele on an X chromosome differ between men and women

men have only one X chromosomes so if the recessive trait is present on it then it will be expressed. They dont have another X to possibly dominate that expression

500

Compare mitosis and meiosis. Include at least three points of comparison

one division vs. 2 division

pair of homologous doesnt occur vs. does

2n vs n

identical daughters vs unique daughters

2 cells vs. 4 cells

somatic cells vs. gametes

growth and repair vs. genetic variation

500

Marty is homozygous dominant for brown hair. Felicia is homozygous recessive for blonde hair. What percent of their offspring will have blonde hair? This is the genotypes of their children.

What is Bb? 0% blonde

What is the human genome project?

one of the most important scientific accomplishments in history!!

determine the sequence of the human genome(complete genetic information)
