meiosis

Question 1

haploid

Answer 1

only one set of chromosomes

Question 2

homologous

Answer 2

matching chromosomes containing same genes at same loci

Question 3

what are diploid cells undergoing meiosis called?

Answer 3

gonads

Question 4

what is the caveat of homologous chromosomes

Answer 4

they may contain different alleles (variants) for the genes

Question 5

prophase 1

Answer 5

same as prophase
then chromosomes come together in homologous pairs
crossing over occurs alleles are swapped and shuffled

Question 6

methaphase1

Answer 6

same as metaphase

independent assortment on the equator

Question 7

anaphase 1

Answer 7

same as anaphase

crossed over ares seperate

Question 8

telophase 1

Answer 8

same as telophase
then short interphase after when chromosomes uncoil
each nucleus contains half num of chromosomes but each has 2 chromatids

Question 9

prophase 2

Answer 9

if nuclear envelopes reformed then they break down
chromosomes coil and condense
chromatids no longer identical
spindles form

Question 10

metaphase 2

Answer 10

chromosomes attach at centromere

chromatids randomly arranged

Question 11

anaphase 2

Answer 11

centromeres divide
chromatids pulled away by motor proteins
randomly segregated

Question 12

telophase 2

Answer 12

nuclear envelopes form around four haploid nuclei

the two cells divide making 4
