Phenotype

Science / Biology / Phenotype: The observed properties or outward appearance of a trait. The physical expression of the alleles posessed by an organism.

Pleiotropy

Science / Genetics / Pleiotropy: The phenomenon of variable phenotypes for a number of distinct and seemingly unrelated phenotypic effects. MORE

Heterogeneity

Science / Genetics / Heterogeneity: The production of identical or similar phenotypes by different genetic mechanisms. MORE

Dominant

Science / Biology / Dominant: Refers to an allele of a gene that is always expressed in heterozygotes. MORE

Genotype

Science / Biology / Genotype: The genetic (alleleic) makeup of an organism with regard to an observed trait. MORE

Phenotypic Plasticity

Science / Marine Biology / Phenotypic Plasticity: The capacity of an individual to produce different phenotypes under different conditions. Non-genetic potential variability within the range of a single individual. MORE

Marker

Science / Genetics / Marker: A gene with a known location on a chromosome and a clear-cut phenotype, used as a point of reference when mapping a new mutant. MORE
