Genetics exam 1 WITH Q&A
ELABORATION UPDATED VERSION!!
Disjunction
 ANSWER : the separation of chromosomes during the anaphase stage of cell division
Non-disjunction
 ANSWER : Error in meiosis in which homologous chromosomes fail to separate.
Aneuploid
 ANSWER : Abnormal number of chromosomes.
Phenotype
 ANSWER : An organism's physical appearance, or visible traits.
Meiosis
 ANSWER : •Cell division that produces reproductive cells in sexually reproducing organisms
•The process of cell division in gametogenesis or sporogenesis during which the diploid number of
chromosomes is reduced to the haploid number.
Mitosis
 ANSWER : A form of cell division producing two progeny cells identical genetically to the parental cellthat is, the production of two cells from one, each having the same chromosome complement as the
parent cell.
gameotogenesis
 ANSWER : process by which gametes are produced through the combination of meiosis and other
maturational changes
Zygonema
 ANSWER : Synapsis
Each pair of homologous chromosomes is known as bivalent
