Q

multiple checkpoints in biochem pathways in the form of intermediate molecules allows for the reaction to be

A

controlled in difference places of the reaction in different manners

17
Q

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?

A

yes, red

18
Q

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?

A

no, white

19
Q

why does A1A2 not function as it should

A

the active site is a little different

20
Q

A2A2: 1 allele, 1 polypeptide and a non functioning second polypeptide. what is the end color

A

red

21
Q

in A2A2, why does it still produce a red coloration?

A

presence of the 1st allele is what it important. the recessive condition produces the non-functional.

22
Q

true mendelian expression is

A

rare

23
Q

incomplete dominance homo of 1 form is red, the hetero is pink (½ expression), other homo
is white
i. Homo 1: __

A

2 red

24
Q

Incomplete: homo of 1 form is red, the hetero is pink (½ expression), other homo
is white. Hetero: __

A

1 red, 1 white

25
Q

Incomplete: homo of 1 form is red, the hetero is pink (½ expression), other homo
is white. homo 2 __

A

2 white

26
Q

the difference with incomplete and codominance is the individual with the recessive genotype still produces a ___ polypeptide

A

functioning

27
Q

can you look at the genes themselves to predict which one is dominant or recessive

A

no

28
Q

organismal phenotype is due to the phenotype of its __

A

cells

29
Q

determination of dominance v recessive is done by looking at the ___ individual

A

heterozygous

30
Q

to determine which gene is dominate v recessive what must you do

A

ID the heterozygous individual and create crosses

31
Q

term for the most common phenotype seen within a population

A

Predominant

32
Q

T/F: sometimes the mendelian dominate is not the most common (pre dominant)

A

True

33
Q

T/F: Dominance means the you are the most common form

A

False
