Genetics Flashcards
discrete units of hereditary information consisting of a specific nucleotide sequence of DNA, and represents a character such as eye color
Genes
alternative forms of a gene, represents a trait
allele
who proposed Laws of Heredity
Gregor Johann Mendel
Unit determiners come in _____
pairs
The physical manifestation of a trait
phenotype
Where if two alleles differ, the dominant one is fully manifested and the recessive isnt seen at all
Law of Dominance
Phenomenon explained by meiosis where two alleles are segregated
Law of Segregation
Where inheritance of one allele will not affect the other
Law of Independent Assortment
Where there is intermediateness between alleles
Incomplete dominance
Both alleles contribute to the appearance without blending
Codominance
Possibility of having more than two traits (blood types)
Multiple alleles
Collection of two or more genes that exert effects on single phenotype
Polygenic inheritance
Trait found in sex chromosomes
Sex-linked traits
Traits’ dominance depends on the sex
Sex-influenced
Traits manifested in only one sex
Sex-limited
