Question | Answer |
incomplete dominance | a condition in which neither allele for a gene completely conceals the presence of the other; it results in intermediate expression of a trait |
co-dominance | the condition in which both alleles for a trait are equally expressed in a heterozygote; both alleles are dominant heterozygous advantage |
multiple alleles | a gene with more than two alleles |
polygenic inheritance | a trait that is controlled by more than one gene |
continuous variation | a range of variation in one trait resulting from the activity of many genes |
linked genes | genes that are on the same chromosome and that tend to be inherited together |
linkage group | all genes on any one chromosome |
chromosome mapping | the process used to determine the relative location of genes on chromosomes |
sex-linked trait | a trait controlled by genes on the X or the Y chromosome |
X-linked & Y-linked | a trait found on either the X chromosome or the Y chromosome |
Barr bodies | structure in the female cell in which one of the X chromosomes is inactive. The inactive X chromosome is tightly condensed |
inactive X chromosome | a Barr body |
genome | the complete sequence of nucleotides in an organism |
bioinformatics | a field of study that deals with using computer technology to create and analyze large databases of information |
genomics | the study of genomes and the complex interactions of genes that result in phenotypes |
genetic profile | the complete genotype of an individual, including various mutations |
single nucleotide polymorphism (SNP) | a type of genetic variation that results from changes in the DNA at single locations. |
proteome | all of the proteins in an organism |
proteomics | the study of the three-dimensional shape and function of all cellular proteins |
epigenetics | the study of how changes in the inheritance of certain traits or phenotypes are based on changes to gene function and not to changes in DNA sequence |
epigenome | cellular material that is not part of the genome but influences whether a gene is “turned on” or “turned off ” |
microarrays | a technique used to study differences in gene activity of DNA |
heterozygous advantage | a situation in which heterozygous individuals have an advantage over both homozygous dominant and homozygous recessive individuals |
