What is the substance carrying an organisms genetic code? | DNA
| What is the name for chromosomes that contain different versions of the same genes? | homologous
| What is the name for a length of DNA that contains the code for a specific trait? | gene
| What do we call different versions of the same gene? | allele
| Draw and label a nucleotide. | ...
| What is the name for a genetically or environmentally determined characteristic? | trait or phenotype
| What is the name for cell used for sexual reproduction that carries a random selection of half of the organisms genetic information? | gamete
| During meiosis, chromosomes can randomly line up on either side of the equator of the cell to create different variations of chromosomes in the gamete. What is this process called? | Independent assortment
| During meiosis homologous pairs of chromosomes, swap alleles to create variation between the parents and offspring. What is this process called? | Crossing over
| What type of cell division creates clone cells for healing and repair | mitosis
| What type of cell division that creates cells with half the genetic information randomly shuffled? | meiosis
| What feature of a population allows it to adapt to changes in their environment? | variation
| Invasive species, drought, floods, pollution, decrease in available food, are all examples of what? | Selection pressure
| What are 2 key differences between the 2 types of cell division? | Number of cell divisions/daughter cells, one creates variation, the other creates clones.
| What biological catalysts are responsible for driving DNA replication? | Enzymes
| What do we call it when a newly replicated DNA strand contains half of an old strand of DNA? | semi-conservative replication
| What is the process that causes small changes in the allele frequency of a population? | Natural or artificial selection
| What is it called when changes in allele frequency build up over time and can result in a new species being formed? | Evolution |
