Multiples Alleles
3 or more alleles to choose from
each trait only contains 2 alleles
one allele from dad
one allele from mom

Multiple Alleles
codominant- both traits are showing up a new phenotype
incomplete dominance-mix of traits or a blend of traits as a new phenotype
8
Beyond Mendel Genetics
Incomplete Dominance=red flower x white flower= pink flower
(RR x WW=RW)
Codominance-both color traits showed up
BB x WW=BW (white cow with a brown spot
9
Codominance
both colors showed up in the roan cattle offspring
BB x WW=BW
In blood types: AA x BB=AB
Ao x Bo= AB
10
Incomplete Dominance
offspring flowers are neither red nor while
a mix of red and white which is pink
RR x WW = RW

Interpreting Punnett Square
both parents are heterozygous, Bb x Bb
if B-represent a brown eye allele, brown eyes is dominant
offspring: BB(brown eyes); Bb(brown eyes); bb(blue eyes-the only recessive)
