| Question | Answer |
|---|---|
| A mutation that causes death of the organism | Lethal Mutation |
| What type of mutation does not affect the offspring? | Somatic Mutation |
| Downs Syndrome is caused by ? | One too many chromosomes |
| Inbreeding is to breeds as crossbreeding is to | Hybrids |
| When a person selects and mates a dog from different breeds that have the characteristics whey want in the new breed, | Crossbreeding |
| Which one of these does not belong with the others: Embryo splitting, asexual reproduction, identical twins and hybrid. | Hybrid the other three have to do with cloning. |
| Splitting frogs and cattle embryos are a step in what process? | Cloning |
| Fraternal twins have the same | Parents |
| The process of genetic engineering can be used for | good or evil |
| What is the Human Genome Project? | A scientific effort to map all human genes |
| Any change in an organism's genetic materail | Mutation |
| A mutation that changes the sequence of bases in a gene | Gene Mutation |
| If a person has the gene but not the disease | Carrier |
| A mutation that occurs in a gamete or gamete forming cell. | gern mutation |
| A mutation in a cell that does not produce gametes | somatic mutation |
| a change involving the number of genes or the arrangement of genes on a chromosome. | Chromosomal Change |
| having two sets of chromosomes | diploid |
| characteristics referring to the number of sets of chromosomes in a cell. | ploidy |
| Twins that develop from a single zygote | Identical twins |
| Who in the Bible used selective breeding | Jacob |
| Cloning is what form of reproduction | asexual |
| Caused by a mutation that affects pigments | albinism |
| the choosing of organisms that are purebred for a desired characteristic | breed |
| the mating of an organism with a close relative | inbreeding |
| another name for hybridization | genome |
| the condition in which an offspring is stronger than its parent | Hybrid vigor |
| the use of special techniques to control the genetic makeup of an organism | genetic engineering |
| a group of genetically identical organisms produced by asexual reproduction. | Clones |
| the result of a pregnancy in which two sperm unite with two different eggs and form genetically unique organisms | Fraternal twins |
| a complete set of an organism's genes | Genome |
| Mutations can happen at | anytime |
| Mutations are considered | harmful |
| Sometimes mutations do not appear to affect the | organisms |
| what attempts to preserve the special characteristics of a breed | Inbreeding |
| Man has used what kind of principles without understanding how they work. | Genetic principles |
| Livestock breeders need to go where in order to learn how to breed. | college |
| Which cell is most likely to be differentiated? | Human skin cell |
| Fraternal twins have the same? | Parents |
| List some recessive genetic disorders | albinism, cystic fibrosis, and hemophilia |
| How do Scientist use genetic engineering in diabetes? | they place the genes for insulin in bacteria and collect the insulin produced. |
| Stem cells can become | Many type of cells |
| What is genome | a complete set of an organism's genes |
| A change in the sequence of bases that make up the gene | gene mutation |
| the use of genetic engineering to correct defective genes is called | Gene therapy |
| Why does a farmer clone his crops? | it has desirable traits that he wants to maintain. |
| Doe Genetic engineering hold the answer to all human problems? | No, because our sin nature is still a part of use and no genetic engineering will change that. |
| Explain the difference between a somatic stem cell and a embryonic stem cell | One uses tissue from humans and doesn't take a life the other takes the life of an unborn baby. |
