7.4 Study guide

Question 1

meiosis

Answer 1

process of creating gametes for sexual reproduction.

Question 2

mitosis

Answer 2

process of creating genetically identical offspring

Question 3

prophase I

Answer 3

chromatin condenses, crossing over occurs, spindle fiber begins to form

Question 4

metaphase I

Answer 4

homologous chromosomes line up, independent assortment occurs, spindle fibers attach

Question 5

anaphase I

Answer 5

homologous chromosomes are pulled to opposite ends of the cell,

Question 6

telophase/cytokinesis I

Answer 6

produces 2 haploid cells

Question 7

metaphase II

Answer 7

sister chromatids line up, spindle fibers attach

Question 8

anaphase II

Answer 8

sister chromatids are separated and pulled to opposite ends of the cell

Question 9

telophase/cytokinesis II

Answer 9

produces 4 genetically varied haploid cells

Question 10

fertilization

Answer 10

2 haploid gametes come together to produce a diploid cell.

Question 11

diploid

Answer 11

cell has 2 copies of each chromosome

Question 12

haploid

Answer 12

cell has 1 copy of each chromosome

Question 13

crossing over

Answer 13

the process in which homologous chromosomes swap alleles with each other, causing genetic variation

Question 14

independent assortment

Answer 14

chromosomes line up in different combinations during metaphase I, causing genetic variation

Question 15

gamete

Answer 15

haploid sex cell
