| chromosomes | ||
| the scientific study of heredity | ||
| the process in which the male and female reproductive cells join together in sexual reproduction | ||
| organisms that produce offspring identical to themselves through self-pollination | ||
| a specific chracteristic | ||
| crosses between parenrts with different traits | ||
| chemical factors that determine traits | ||
| the different forms of a gene | ||
| states that some alleles are dominant and others are reccesive | ||
| separation of alleles during gamete formation | ||
| sex cells | ||
| the likelihood that a particular event will occur | ||
| to predict the outcomes of genetic crosses | ||
| a diagram that can determine the possible gene combinations | ||
| organisms that have two identical alleles for a particular trait | ||
| organisms that have two different alleles for the same trait | ||
| physical characteristics | ||
| genetic makeup | ||
| states that genes for different traits can segregate independently during the formation of gametes and helps account for the many genetic variations observed in pants, animals, and other organisms | ||
| when one allele is not completly dominant over another | ||
| when both alleles contribute to the phenotype | ||
| when genes have more than two alleles | ||
| traits controlled by two or more genes | ||
| term used to refer to chromosomes that each have a corresponding chromosome from the opposite-sex parent | ||
| a cell that contains both sets of homologous chromosomes | ||
| a cell that has one set of homologous chromosomes, a cell that has a single set of chromosomes and therefore only 1 set of genes | ||
| a process of reduction division in which the number of chromosomes is cut in half through the separation of homologous chromosomes in a diploid cell | ||
| (prophase)structure of chromosome paired with its corresponding homologous chromosome | ||
| process in which homologous chromosomes exchange chromatids in meiosis | ||
| diagram showing the relative locations of each known gene on a particular chromosome |
