Chapter 5 lecture Flashcards
What does it mean when more mutants are able to be tested
a more completed pathway can be shown
If a AaBb and aabb crossed what are the genotype and what are the parental and nonparental phenotypes
AaBb Parental
Aabb Nonparental
aaBb Nonparental
aabb Parental
If Nonparental and Parental are equal to each other what does that mean
The 2 genes are not linked or linked but far away
If there are no Nonparental and only Parental types what does that mean
Genes are closely linked and cannot seperate
If there are less nonparental than parents what does that mean
Genes are linked
How to find the distance of a gene for a 2 point mapping
nonparental/(nonparental+parental)*100
What is the gametes of the following without crossover
a B *aabb
A b
aB, aB, Ab, Ab
What is the gametes of the following with crossover and identify the types
a B *aabb
A b
aB a mutant
ab double mutant
AB WT
Ab b mutant
Trans configuration
a B
A b
Cis configuration
a b
A B
What type of configuration does an a mutant crossed with a b mutant create
trans
What type of configuration does a WT and aabb create
cis
recombinant class
new class that parents did not have
What gametes does AaBbCc*aabbcc, what ratio, what is the mutant or WT and determine between parental and nonparental combos
ABC 1/8 WT Parental
abc 1/8 triple mutant Parental
ABc 1/8 c mutant Nonparental
abC 1/8 ab mutant Nonparental
AbC 1/8 b mutant Nonparental
aBc 1/8 ac mutant Nonparental
Abc 1/8 bc mutant Nonparental
aBc 1/8 a mutant Nonparental
What is the F1 and F2 if F1 is testcrossed and identify on F2 Mutant or WT and Parental or Nonparental and ratios if
_____A ___B X _____a ___b
_____A ___B _____a ___b
F1
_____A ___b X _____a ___b
_____a ___B _____a ___b
F2
_____A ___b _____a ___B _____A ___B _____a ___b
_____a ___b _____a ___b _____a ___b _____a ___b
