1
Q
Genes come in multiple
forms called…
A
alleles
2
Q
Genes are located on…
A
chromosomes
3
Q
Genetic information is…
A
transferred from DNA to RNA to protein
4
Q
meiosis 1
A
segregate the homologous chromosomes
5
Q
meiosis 2
A
separate the sister chromatids
6
Q
Null/Amorphic Alleles
A
A nonfunctional protein is produced OR no protein is produced
7
Q
Hypomorphic Alleles
A
A poorly functioning protein is produced OR reduced amounts of a normally functioning
protein is produced 39
8
Q
multiplication rule
A
and
9
Q
addition rule
A
or
10
Q
Dominant Mutations Often Involve…
A
Gain/Change of Gene Function
11
Q
Recessive Mutations Often involve…
A
loss of gene function
12
Q
Dominant Hypermorphic Alleles
A
- Negative phenotypic consequences due to the over- production of a normal protein OR
- Negative phenotypic consequences due to the production of a protein with increased activity levels
13
Q
Neomorphic Alleles
A
- Negative phenotypic consequences due to the presence of an altered protein that has a new function
- Negative phenotypic consequences when the altered protein interferes with the wildtype protein (Dominant-negative allele)
14
Q
For traits that are rare and dominant, affected
individuals are most likely to be…
A
heterozygous
