Unformatted text preview: BIO 118 Genetics Vocabulary GENE = locus (plural- loci) = complementation group: a position on a chromosome where the DNA sequence contains regulatory and protein-coding information CHROMOSOME: a long DNA molecule with many genes along its length, and other regions of DNA sequence that contribute to its stability and proper segregation during cell divisions. ALLELE: the specific DNA sequence of a given gene. Slight differences in sequence can lead to gene products with altered function. The product synthesized from a wild-type allele has normal function; a mutant allele may fail to synthesize a gene product, or may produce one that has altered function. PLOIDY: the number of chromosome sets in each cell of an organism. Humans are diploid , with two copies of every chromosome. Our gametes (sperm and egg) are haploid , with one copy of every chromosome. Many plants are polyploid...
