Exam 1 Lab Component Flashcards
Model organism attributes
short generation time lots of offspring easily obtainable/maintain genetic variation bioethical considerations well annotated genome
ploidy
multiple of haploid set
euploid
exactly matches a multiple of the haploid set
autosomes
chromosomes 1-22
aneuploidy
has a missing or extra chromosomes
nullisomy
loss of one homologous pair -lethal
monosomy
loss of a signal chromosome -Turner’s syndrome
trisomy
3 homologous present - Down’s Syndrome
tetrasomy
extra chromosome pair 4 copies XXXY in males
homologous chromosomes
carry the same genes
2 homologs may…
carry 2 different alleles
Metacenter
centromere in center
submetacenter
centromere offset
telocentric
centromere in telomere region
acrocentric
centromere toward end
karyotype
representation of all chromosomes in a cell
cytogenetics
study of the structure of chromosomes
