Chiasmata

Answer 21

place where 2 homologous chromosomes cross

Question 22

Crossing Over

Answer 22

exchange of genetic material between homologous chromosomes

Question 23

Nondisjuction

Answer 23

chromosomes fail to separate properly

Question 24

Alleles

Answer 24

vary in sequence of nucleotides at the specific locus of a gene

Question 25

Law of Segregation

Answer 25

during meiosis alleles segregate: homologous chromosomes separate
(anaphase 1)

Extranuclear Genes

Answer 31

genes Found in organelles in the cytoplasm
