Reproduction System Genetic Definitions

Mendelian Traits autosomal/dominant/recessive inheritance patterns
Non-Mendelian Traits Any other inheritance pattern
Phenocopy similar phenotype produced by some non-genetic causes
Genocopy similar phenotype produced by different genotypes
Allelic Heterogeneity similar phenotypes produced by different mutaiots at the same gene
Polymorphism multiple alleles for a gene in a population each with an allelic frequancy above 5%
Locus Heterogeneity (polygenic traits) similar phenotypes produced by mutations at different gene loci
Multifactorial traits characteristics controlled by multiple factors, both genetic and environmental
polygenic traits phenotypes determined by multiple genes
Pleiotropy for a single gene to control multiple traits
codominance different alleles for a gene that impart independent effects on phenotypes
mitochondrial traits determined by mitochondrial genes (maternal inheritance)
anticipation a mutant phenotype that increases in severity each generation due to trinucleotide repeat expansion
epigenic imprinting a mutant genotype with a different phenotype depending on context (for instance, the sex of the patient)
X-linked recessive a recessive allele carried by the X chromosome, mostly affecting males, never passed from father to son
X-linked dominant a dominant allele carried by the X chromosome, affecting females twice as often as males, never passed from fater to son
Sex-influenced traits genetic traits whose clinical manifestations or severity are influenced by the sex of the affected individual
Sex-limited traits traits restricted to one sex, although genotype can be present in either sex
