Ch13 Flashcards
A widow peak is a trait control by blank genes
One/single
The body cell of humans chromosomes contains blank number of chromosomes
23
In the case of sex linked trait only blank can be carriers
Females
In blank a recessive allele on the X chromosomes often has no matching allele on the Y chromosomes
Males
The blank thing determined by the genes carried in sex linked chromosomes is a person gender
One of many
Color blindness is a trait controlled by a blank allele on the X chromosomes
Recessive
The sex chromosomes carries by a human egg will always be an blank chromosomes
X
A person who has recessive and one dominant allele for a trait is called
Carrier
The only pair of human chromosomes that do not always match up
Sex chromosomes
Genes found on the X and Y chromosomes are often called blank genes
Sex linked
What type of allele and what effects the body in cystic fibrosis
Recessive
Abnormally thick mucas
What type of allele and what effects the body in sickle cell disease
Codominant
Abnormal hemoglobin
What type of allele and what effects the body in hemophilia
Reccesive
Blood clots poorly
How does a person with one sickle cell allele differ from someone with two
One sick cell means you have normal and abnormal but two means you have the disease
Why is hemophilia more common in makes then females
Sex linked disorder
What causes Down syndrome
They have extra copy of chromosomes 21 in every cell
An abnormal condition a person inherits through genes or chromosomes
Genetic disorder
Is a picture of all the chromomsomea in cell
Karytype
A chart or family tree the tracks which members of a family will have a specific trait
Pedigree
What is a genetic disorder that results when two muated alleles are inherited
Cystic fibrosis
What is a genetic disorder that results from having one extra chromosomes
Down syndrome
What is not a normal protein found in people with sickle cell disease
Hemoglobin
Which is not a cause oh human genetic disorders
Abnormal hemoglobin
A couple that have a family history of a genetic disorder might wish to receive advice from a
Genetic counselor
The allele for a sickle cell trait is blank with the normal allele
Codominant
Blank is a genetic disorder caused by a reccesivev allele on the X chromomsomes
Hemoplila
A doctor may use blank to examine the chromomsomes in a cell
Karytype
A condition in which a person skin hair and eyes lack normal coloring
Albinism
What are two types of genetic breeding how do they compare
Breeding and hybridization they give you desired traits
What is cloning
An organism that has the exact same genes from the organism it was produced from is created
How are bacteria used in genetic engineering
Scientist insert the DNA for the human insulin gene into the plasmid of a bacteria
How could gene therapy someday be used to treat genetic disorders
Inserting copies of a gene directly into a person cells
Organism that has exactly I the same genes as the organism from which it was produced
Gene
Process of inserting copied of a gene directly into the cells of a perish with a genetic disorder
Gene therapy
The process of selecting organisms with desired traits to be parents of the next generation
Selective breeding
Crossing two genetically different organisms
Hybridization
Process by which genes from one organism are the transferred into the DNA of another organism
Genetic engineering
Is the study of the principles about what is right and wrong fair and unfair
Ethics
An organism full sett of DNA is it’s
Genome
Some people fear health insurance companies or employers could use a persons genetic information to blank against him or her
Discriminate
Selected fragments of DNA from a persons cells can be used to produce a unique pattern called a DNA
Fingerprint
DNA technology used in the human genome project can show whether people are
Related
Identical twin have blank DNA
Identical
A Persons medical record may contain information about the persons blank
Lifestyle
The goal of the human genome project was to identify the DNA sequence of the blank human genome
Entire
Genetic fingerprints can be used to blank skeletal remains
Identify
Te genetic information nondiscrimarion cat made it bonks for health insurance companies and employers to tell an individual to have a genetic tests done
Illegal
An organism full set of DNA
Genome
Using genetic information in a fair and just way
Ethics
What is the genetic information nondiscrimation act
Makes it illegal for health insurance companies to discrimimnate against individual based on genetic information
Describe concerns about the increased use and avalibility of genetic information
Concerns are that the government might use DNA in other ways such as in a criminal case or paternity case
What are uses of DNA finger printing
Tie people to crimes and can identify skeletal remains
What is a DNA fingerprint
Selected fragments from in a person DNA are used to produce this pattern
What was the main goal of the human genome project
Was to identify DNA sequence of the entire human genome
