Non-Mendelian Flashcards
What is Incomplete Dominance
When an organism is heterozygous for a trait, but instead of displaying one phenotype, it displays a mixture of both possible phenotypes
Example of Incomplete Dominance
Red Rose + White Rose = Pink Rose
What is Codominance
When two alleles are present in an organism and both phenotypes are shown in the organism
Example of Codominance
Black Chicken + White Chicken = Speckled Chicken that is black and white
Incomplete Dominance has how many phenotypes
Three
Codominance has how many phenotypes
Three
What is multiple alleles
When there are more than two alleles for a gene in a population
Example of multiple alleles
Blood typing
What are sex linked traits
Traits that are controlled by genes found on the sex chromosomes (X chromosomes)
Sex linked traits are most often found in the ______ chromosome
X
In sex linked traits, who is always the carrier
Females
In sex linked traits, the male either ______ the trait, or ______ the trait
Has ; doesn’t have
In sex linked traits, the trait is passed by ____________
X chromosomes
In pedigrees, a circle represents a ______
Female
In a pedigree, a square represents a ______
Male
In a recessive trait pedigree, a shaded circle or square represents an ______ individual
Affected
In a recessive trait pedigree, a half shaded shape represents a _______ of the trait
Carrier
Mendel’s rule of dominance is ______
Rare
Multiple alleles is a _____________
Range of values ; a scale ; short to tall
How do you identify what kind of pedigree a pedigree is
Compare affected males to females, count how many are affected total, count how many phenotypes there are, check if it skips a generation
Where are antigens located
On the red blood cells
Where are antibodies located
In your blood
Blood type A genotypes for homozygous and heterozygous
Homo - II (A above both Is)
Hetero - Ii (A above first I)
Blood type B homozygous and heterozygous genotypes
Homo - II (B above both Is)
Hetero - Ii (B above first I)
Blood type AB genotype
II (A above first I, B above second I)
Blood type O genotype
ii
The antigens on type A blood are type ______ and the antibodies are type ______
A ; B
The antigens on type B blood are type ______, and the antibodies are type ______
B ; A
The antigens on type AB blood are _______ and the antibodies are type ______
A + B ; none, there are no antibodies present
The antigens on type O blood are type ______ and the antibodies are type _______
None, there are no antigens present ; A + B
Polygenic means…
Many genes that decide one trait
If blood type is ______ then the blood has Rh protein, if blood type is ______ then blood doesn’t have Rh protein
Positive ; negative
