FINAL EXAM Flashcards
genetics
The Hardy-Weinberg Theorem
States allele frequencies in a population will not change from generation to generation.
genetics
The conclusions of the Hardy-Weinberg Theorem apply only when the population conforms to the following assumptions:
- No natural selection
- No mutations
- No migration
- Random mating
- Infinitely large pop. size
genetics
Translocation
Translocation means a change in location. It often refers to genetics, when part of a chromosome is transferred to another chromosome.
genetics
Aneuploidy
Cell is missing 1 chromosome, or has 1 chromosome too many. N does not equal 46.
genetics
Polyploidy
Refers to having 3+ whole sets of chromosomes. Rare in humans.
genetics
Trisomy
Aneuploidy where there is an extra chromo.
genetics
Monosomy
Aneuploidy where there is one missing chromo.
genetics
Duplication
A type of mutation in which one or more copies of a DNA segment is produced.
genetics
Nondisjunction
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during cell division.
plants
Xylem vs Phloem.
Xylem distributes H2O and MINERALS from bottom up(one-way), phloem distributes CO2 and food from leaf down (two-way)
