| Question | Answer |
| Petunias that are pink from red and white parents are an example of | _Incomplete__ dominance where
neither allele is dominant. |
| Chickens with black and white feathers display | __Codominance__ where both alleles share dominance. |
| The many different colors of rabbit coats are an example of | __Multiple Alleles___ determining coat
color and are the result of the interaction between two or more alleles. |
| __Polygenic_ traits are | when more than one trait interacts and human eye color is an example. |
| Environmental conditions can also impact the genes and the butterfly is a good example. The wings are
light colored when the temperature is | high as in _Summer___ and dark when the temperature is low as
in fall. |
| Genes that occur very close together on a chromosome are said to be | linked |
| The purpose of meiosis is to | half the genetic information |
| Duplicated chromosomes are called | __Homologous__. |
| During prophase I of meiosis the homologous chromosomes pair up to form a | Tetrad |
| Crossing over occurs during | ___Prophase I__ of meiosis. |
| The cells become haploid during | __Telophase I__ of meiosis. |
| At the end of meiosis II there are four identical/unique haploid cells. | Unique |
| A situation in which a gene has more than two alleles is known as | Multiple Alleles |
| A pink-flowered Mirabilis plant (RW) is crossed white a white-flowered Mirabilis (WW). What is the chance that a seed from this cross will produce a red-flowered plant? | 0 |
| The illustration below represents what stage of meiosis? | metaphase 1 |
| Unlike mitosis, meiosis in male mammals results in the formation of | four haploid gametes |
| Gene map | The relative locations of genes on a chromosome |
| Suppose that an organism has the diploid number 2N=8. How many chromosomes do this organism's gametes contain? | 4 chromosomes. |
| What happens to the chromosome number during meiosis? | It halves |
| During which phase of meiosis is the chromosome number reduced? | anaphase 1 |
| Two pink-flowering plants are crossed. The offspring flower as follows: 25% red, 25% white, and 50% pink. What pattern of inheritance does flower color in these flowers follow? | Incomplete dominance |
| Which of the following is used to construct a gene map? | Recombination rate |
| Alleles for the same trait are separated from each other during the process of | Meiosis 1 |
| How many map units apart are genes A and D? | 8 |
| Which gene map best reflects the student's data? | D. C B A D |
