Question | Answer |
What is the difference between inherited traits and environmentally influenced traits? | Inherited traits are directly passed from generation/parent to offspring. Man-made items or nature impacting traits are environmental. |
What is a carrier? | Someone who carries a disease without being affected. This disease can be passed on. |
What are female and male sex chromosomes? | Chromosomes that determine a person's gender. xy chromosome-male,xx chromosome-female |
How does Down Syndrome occur? | An extra cell is found in each cell, resulting in 47 cells rather than 46. This is due to an extra copy of chromosome 21. |
What is sickle cell anemia? | An inherited disease which causes blood cells to become "sickle" shaped. These cells clog in narrow veins, stopping blood flow. |
What is DNA, and how is it formed? | DNA is a string of chemical bases(Adenine, Thymine, Cytosine, Guanine) which instruct cell traits. The DNA builds into a double helix(spiral ladder) formation. |
What rules must be followed when ATCG bases are paired? | AT bases must always be paired and CG bases must always be paired. |
What is a karyotype? | The appearance of a chromosome in the cell nucleus. |
What is selective breeding? | Mating two organisms with desired traits to produce offspring with better results. |
What is inbreeding? | Breeding offspring with a family member that has desired traits to create a purebred result. |
What is cloning? | Taking the nucleus of an organism and inserting it into another cell to make an exact genetically copied result. |
what is a genome? | All of the DNA in one cell of an organism. |
What was the purpose of the Human Genome Project? | To provide an encyclopedia of mapped human DNA that can be used ti cure diseases. The human body's functions will also be shown. |
