Gene linkage and recombination Flashcards
1
Q
dosage compensation
A
making it so XY and XX species have the same amount of transcription
2
Q
Barr body
A
inactive X chromosome created by histones
3
Q
non-disjunction
A
chromosome separation fails during meiosis
4
Q
trisomy
A
3 homologs instead of 2
5
Q
monomy
A
1 homolog instead of 2
6
Q
linked genes
A
the genes are physically linked on the same chromosome
7
Q
map units
A
units of distance on chromosome; % of offspring with non parental genotype
8
Q
polygenic trait
A
1 trait is caused by several genes
9
Q
quantitative variation
A
often determined by polygenic control
10
Q
epistasis
A
complex interactions between genes and traits
11
Q
genome wide association study
A
correlate nucleotide difference in DNA from individual to occurrence/strength of trait
