Exceptions to Mendel's principles
Incomplete dominance- where one allele is not completely dominant over another.
Codominance- the phenotype produced by both alleles are clearly expressed.
Multiple alleles- a gene with more than two alleles
Polygenetic traits- traits controlled by two or more genes
Genes and environment- environmental conditions can affect gene expression and influence genetically determined traits.
1.) a.) incomplete dominance is where one allele is not dominant in comparison to the others in red and white flowers they are incomplete dominance because they are (RW)
2.) a.) it provides a plan for that phenotype
b.) the butter fly may not hatch because they hatch a a certain warm temperature
