a picture of chromosomes displayed in pairs. You can distinguish the gender by the 23rd set of chromosomes. 2 large = XX 1 large, 1 small = XY |

What is incomplete dominance? Give an example. |
When 2 dominant alleles blend to make a 3rd phenotype. EX: Red = RR White = WW Pink = PW |
|
|
What is co-dominance? Give an example. |
When both phenotypes show together. EX: Black = BB White = WW Spotted = BW |
|

phenotype, genotype |
|
|
What is a carrier? What is their genotype? |
someone who carries the recessive allele EX: Bb |
|
|
If someone is a carrier in a pedigree, the trait must be ___________. |
recessive |
|
|
If you have a male carrier, then what it eh inheritance pattern (AD, AR, XD, XR)? |
Autosomal Recessive |
|
|
What are the most common pedigree symbols: -male & female -affected male & female -male carrier & female carrier |
-M: [], colored in, and dotted. -F: O, colored in, and dotted |
