| Mendel's Work | ||
| #1 | This type of organism is the offspring of many generations that have the same trait | Purebred |
| #2 | the combination of two alleles makes this | A gene |
| #3 | The ___________ allele is one whose trait always shows up in an organism when the allele is present | dominant allele |
| #4 | During Mendel's pea experiment Mendel crossed a ______ tall pea plant with a _____ short pea plant (the p generation). | purebred tall, purebred short |
| #5 | In Mendel's experiments, during the F1 generation why were all of the pea plants tall? | Cross TT with tt will result in all offspring being hybrids, Tt, which means they will be have the dominant phenotype, but can still carry the recessive allele. |
| Probability | ||
| #1 | What is the chart that shows all of the possible combinations of alleles that can result from a genetic cross | Punnett Square |
| #2 | The physical appearance of visual traits | phenotype |
| #3 | The genetic make up or allele combinations | genotype |
| #4 | In ____________ neither alleles are dominant or recessive. | co-dominance |
| #5 | another term for hybrid where a genotype has two different alleles | heterozygous |
| The Cell and Inheritance | ||
| #1 | combination of genetic material from two parents that results in the production of a new organism | sexual reproduction |
| #2 | what is meiosis | production of sex cells |
| #3 | How many cells are created at the end of meiosis? | 4 |
| #4 | A ________ cell contains two sets of chromosomes, one set from each parent | diploid |
| #5 | Where are genes found | on chromosomes |
| Genes, DNA, and Proteins | ||
| #1 | During this process the cell uses information from a gene on a chromosome to produce a specific protein. | protein synthesis |
| #2 | __________ RNA copies the coded message from the DNA in the nucleus and carries the message to the ribosome in the cytoplasm. | messenger RNA |
| #3 | __________ RNA carries amino acids to the ribosome and adds them to the growing protein. | transfer RNA |
| #4 | During protein synthesis, adenine pairs with what nitrogen base | uracil (thymine is replaced by uracil in RNA) |
| #5 | what are the 3 ways a mutation can occur? | substitution, deletion, addition |
| Random | ||
| #1 | The likelihood that a particular event will occur is called ______. | probability |
| #2 | Following meiosis 1 there are currently __ cells produced | 2 |
| #3 | what is independence of events? | when each trial or event happens independently and has no affect on the next trial Ex: tossing a coin |
| #4 | What base pairs would pair with GCTTAA? | CGAAUU |
| #5 | Where does transfer RNA perform its function? | cytoplasm |
| Final Question | |
| In rabbits, the allele for a spotted coat is dominant over the allele for a solid-colored coat. A heterozygous spotted coat rabbit was crossed with a solid-colored coat rabbit. what are the possible genotypes and phenotypes of the offsprings? | genotypes: Rr and rr Phenotypes: Spotted (50%) solid (50%) |
