Topic 10 Flashcards
1
Q
linkage
A
two genes/alleles linked together, present on same chromosome. cannot assort independantly
- (tendancy of chromosomes to stick together)
2
Q
crossing over
A
intrachromosomal recombo during meiosis when a homologous pair make contact, exchange of genetic variation
3
Q
uniparental inheritance
A
genes to all offspring from one parent only
- genomic imprinting
- mtDNA
4
Q
- genomic imprinting
A
- genomic imprint
. gene inactivation (maternal or paternal)
. 3 alleic/genotype variants occur
5
Q
- mtDNA
A
- mtDNA
. maternal inheritance, mitochondrial disease
. replication and transmission of extrachrimosomal genetic info from mitochondria,
. phenotypic difference controlled by cytoplasmic factors
