Chromosome Gene Flashcards
Nature v Nurture
Environment influences the expression of genes
Multiple Allele Trait
Some traits have more than 2 allele choices
Polygenetic trait
Some traits are determined by more than one gene
Complete Dominance
Dominant masks the recessive one
Incomplete Dominance
Heterozygous organisms with one dominant trait and one recessive show a blended in between trait
Co - Dominance
Both traits are expressed at the same time with no blending
Law of Dominance
Some alleles are dominant and some are recessive. The dominant . trait masks the expression of the recessive trait
Law of Segregation
Alleles of a gene occur in pairs and are separated from each other in meiosis and recombined during fertilization.
Law of Independent Assortment
Each gene pair for a trait is inherited independently of gene pairs for all other traits
