|
CR1
Define: mutation |
any change in an organism's genetic material
|
|
|
CR 2
What type of mutation involves a change in the DNA base sequence? |
gene mutation
|
|
|
CR 3
Which type of mutation, germ or somatic, affects the offspring of an organism? |
germ mutation
|
|
|
CR 4
What genetic disease is famous for affecting European royalty? |
Hemophilia "bleeder's disease"
|
|
|
CR 5
Give a brief description of the following genetic disorders: Down syndrom, hemophilia, Duchenne muscular dystrophy, cystic fibrosis, Tay-Sachs disease |
Look in the book for this.
|
|
|
CR 6
What causes a change in ploidy, a change in DNA base sequences or a change in the number of chromosomes? |
mutation
|
|
|
CR 7
Are dog breeds produced by inbreeding or genetic engineering? |
inbreeding
|
|
|
CR 8
Why are fraternal twins not considered clones? |
They are the result of two sperm and two ova uniting separately. They do not have the same genetic makeup.
|
|
|
CR 9
Give one way in which genetic engineering has already benefited man. |
genetically altered crops: frost-resistant tomatoes, rice containing vitamin A, sweeter potatoes, etc.
|
|
|
CR 10
What is the Human Genome Project? |
Researchers who are studying all twenty-three paris of human chromosomes AND trying to match those genes to all the human traits.
|
|
|
WDYL 1
Which affects more genes, a gene mutation or a chromosomal mutation? |
chromosomal mutation
|
|
|
WDYL 2
Why are somatic mutations generally less important than germ mutations? |
Somatic mutations don't affect future generations; germ mutations do.
|
|
|
WDYL 3
Were Santa Gertrudis cattle deveoped by selective breeding or crossbreeding? |
Crossbreeding. Crossbreeding uses different breeds (shorthorm and Braham); selective breeding would use the same breed
|
|
|
WDYL 4
What are some potential dangers in human genetic engineering? |
Changing a person's genes unnecessarily would be similar to doing unnecessary surgery; people might appear perfect, but would still have a sin nature.
|
|
|
WDYL 5
Why will solving physical problems, such as genetic diseases, not solve the world's problems. |
People still have a sin nature.
|
|
|
WDYL 6
Does the Bible forbid genetic engineering? |
It's OK for plants and animals because man was given dominion over those things. Probably not OK for humans because humans do not have dominion over other humans and we are not to abuse our own bodies.

SS - Define: Mutation
|
a change in the genetic material of a cell
|
|
|
SS - Define: lethal mutation
|
a mutation that causes death
|
|
|
SS - Define: germ mutation
|
a mutation in a gamete or a gamete-forming cell
|
|
|
SS - Define: somatic mutation
|
a mutation that occurs in the body cells (those cells that do not make gametes)
|
|
|
SS - Define: chromosomal change
|
a change involving the number of chromosomes or the number or location of genes in a chromosome
|
|
|
SS - Define: diploid
|
having one pair of each type of chromosome in an orgamism
|
|
|
SS - Define: selective breeding
|
choosing certain organisms with desirable traits to breed in the hope that their offspring will have the desired traits.
|
|
|
SS - Define: inbreeding
|
the mating of closely related organisms
|
|
|
SS - Define: breed
|
a group of organisms that is purebred for certain characteristics
|
|
|
SS - Define: crossbreeding
|
breeding animals from different varieties to produce a breed with traits of both parents
|
|
|
SS - Define: genetic engineering
|
the use of special techniques to control the genetic makeup of an organism
|
|
|
SS - Define: Human Genome Project
|
a project where researchers are studying all twenty-three pairs of human chromosomes AND trying to match those genes to all the human traits.
