Question | Answer |
genetics | the scientific study of heredity |
true-breeding | term used to describe organisms that if allowed to self-pollinate would produce offspring identical to themselves |
trait | a specific characteristic that varies from one individual to another |
hybrid | offspring of crosses between parents with different traits |
gene | sequence of DNA that codes for a protein and therefore determines a trait |
allele | one of a number of different forms of a gene |
segregation | the separation of alleles during gamete formation |
gamete | specialized cell involved in sexual reproduction; sex cell |
sperm | gamete produced by meiosis in the male |
egg | gamete produced by meiosis in the female |
dominant | stronger form of a trait that will always be expressed if it is present. Represented with a capital letter |
recessive | weaker form of a trait that will be expressed only if the dominant form is not present. Represented with a lowercase letter. |
homozygous | term used to refer to an organism that has two identical alleles for a particular trait |
heterozygous | term used to refer to an organism that has two different alleles for the same trait |
phenotype | physical characteristics of an organism |
genotype | genetic makeup or allele letter combination of an organism |
independent assortment | independent segregation or separation of genes during the formation of gametes |
incomplete dominance | situation in which one allele is not completely dominant over another |
probability | the likelihood that a particular event will occur |
Punnett Square | diagram showing the gene combinations that might result from a genetic cross |
codominance | situation in which both alleles of a gene contribute to the phenotype of the organism |
multiple alleles | three or more alleles of the same gene |
polygenic trait | trait controlled by two or more genes |
gene map | diagram showing the relative locations of each known gene on a particular chromosome |
