Human Heredity Flashcards
How did Mendel describe inheritance as
Discrete factors, genes, that are passed along from generation to generation according to simple rules of probability
-complete dominance
What are the five parts of human heredity
- codominant
- incomplete dominant
- multiple alleles
- pleiotropy
- polygenic inheritance
Co dominant
Speckled carnation
Incomplete dominant
Hypercholestrolemia
Multiple alleles
Blood type / with co dominant
Pleiotropy
Sickle cell disease
Polygenic inheritance
Skin color
Def of co dominant alleles
Equally strong and do not mask one another
Def of incomplete dominance
One allele for a specific trait is not completely expressed over its paired allele. This results In a third phenotype the combination of the phenotypes of both alleles
Def of multiple alleles
Three or more alleles that code for the same trait but only two are expressed
Def of Pleiotropy
One gene influences multiple characters
Def of polygenic inheritance
Additive effect of two or more genes on a single phenotypic character: Skin color Height Size Heart health Finger print
