In Arctic Hares, a cream nose with long whiskers is dominant over a brown nose with short whiskers. A female Arctic Hare, who’s homozygous for a brown nose and short whiskers mates with a male bunny rabbit who’s heterozygous for both a cream nose and long whiskers. What is the female’s genotype?	nnww

Codominance	both alleles are equally dominant
Since one allele is not completely dominant over another we can no longer use just one uppercase or lowercase letter like with normal punnett squares. Instead, we have to use two different letters that are both	capitals to show equal dom
Incomplete Dominance	one allele is not completely dom
The heterozygous phenotype is a blended mix between the two	homozygous phenotypes
Multiple Alleles	genes with 2+ alleles
The codominant blood type is	AB
Polygenic Traits	traits controlled by 2+ genes
Autosomes	every other chromosome
X-Linked Traits	X sex chromo trait
heterozygous carrying a recessive trait unaffected	Carrier

whats the second step in figuring out a pedigree?	x linked or autosomal
what does it mean if the symbol is shaded all the way?	expresses trait
what does it mean when the symbol is only half shaded?	carrier of trait
if both parents have a dominant trait then	their kids will have it

What does Homozygous B blood look like	BB
X-Linked traits determine the	sex
A B O are all	alleles
Type O blood is the	uni donor
