10/9 Flashcards
incomplete dominance
1/2 of A1 and 1/2 of A2
incomplete dominance is the __ phenotype between the 2 mating individuals
midpoint
codominance
both A1 and A2 are expressed in heterosexual individual
codominace looks
incomplete
codominance looks incomplete because this could also show a
midpoint
codominance looks incomplete but isn’t because it is how this is expressed is where the __ is
difference
HDL
high density lipids
LDL
low density lipids
what is the bad form of cholesterol
LDL
reactant —> __ –>products
multiple steps of intermediates
cell respiration is known as the fundamental __ __
energy cycle
what is the reverse reaction of cell respiration
photosynthesis
biochem pathways have a lot of steps and lots of intermediates to increase
precision
precision is
the ability to find tune the reaction
biochem pathways have lots of intermediates to have multiple __
check points
multiple checkpoints in biochem pathways in the form of intermediate molecules allows for the reaction to be
controlled in difference places of the reaction in different manners
A1A1: enzyme/homo genes you have 2 copies of the allele which is the enzyme.
does everything function as it should? what is the end color?
yes, red
A1A2 : the polypeptide is a little diff because the genetic makeup of the allele has
been changed. does this function as it should? what is the end color?
no, white
why does A1A2 not function as it should
the active site is a little different
A2A2: 1 allele, 1 polypeptide and a non functioning second polypeptide. what is the end color
red
in A2A2, why does it still produce a red coloration?
presence of the 1st allele is what it important. the recessive condition produces the non-functional.
true mendelian expression is
rare
incomplete dominance homo of 1 form is red, the hetero is pink (½ expression), other homo
is white
i. Homo 1: __
2 red
Incomplete: homo of 1 form is red, the hetero is pink (½ expression), other homo
is white. Hetero: __
1 red, 1 white
Incomplete: homo of 1 form is red, the hetero is pink (½ expression), other homo
is white. homo 2 __
2 white
the difference with incomplete and codominance is the individual with the recessive genotype still produces a ___ polypeptide
functioning
can you look at the genes themselves to predict which one is dominant or recessive
no
organismal phenotype is due to the phenotype of its __
cells
determination of dominance v recessive is done by looking at the ___ individual
heterozygous
to determine which gene is dominate v recessive what must you do
ID the heterozygous individual and create crosses
term for the most common phenotype seen within a population
Predominant
T/F: sometimes the mendelian dominate is not the most common (pre dominant)
True
T/F: Dominance means the you are the most common form
False
