Exceptions to Mendel’s laws. 1) Incomplete dominance Some alleles are not completely dominant and the offspring will have a “blending” of the parents.

Patterns of Inheritance. Dominant Vs. Recessive Dominant gene will always be displayed Recessive gene can “Skip” Generations Need 2 copies of recessive.

 Genes are found on the X AND Y chromosomes.  Genes that are carried on the sex chromosomes are called sex linked genes.

REVIEW GENETICS- the study of heredity. Inheritance Traits are specific characteristics inherited from parents Genes are the factors that determine traits.

There is no dominant allele, There is no recessive allele. Both alleles “blend” to result in a third phenotype.

Non-Mendelian Inheritance Patterns

Incomplete Dominance – 2 traits to a new middle trait BLEND P generation

Codominance – 2 traits show up side by side

Use 2 DIFFERENT letters

Multiple Alleles – More than 2 options for the trait http://www.youtube.com/watch?v=IJ7LBuLR0rg

Sex-Linked Inheritance – carried on the X chromosome Women carry the diseases…but men suffer MOST of the time WHY? Women have an extra X chromosome if they get a bad one…men DON’T Color blindness, hemophilia are classic examples

Pedigrees – shows several generations of a trait
