meiosis

Question 1

use of meiosis

Answer 1

to produce gametes because products are genetically different

Question 2

meiosis 1

Answer 2

PMATC
diploid parent cell divides to make two haploid daughter cells each with 1 chromosome set (consisting of two chromatids in each chromosomes)
chromosomes replicate before meiosis 1

Question 3

meiosis 2

Answer 3

chromatids split to make 4 haploid nuclei (each chromosome consists of one chromatid)

Question 4

how meiosis increases genetic diversity

Answer 4

crossing over
independent assortment

Question 5

independent assortment

Answer 5

random alignment of homologous pairs on the equator in metaphase 1 of meiosis

Question 6

crossing over

Answer 6

during prophase 1 of meiosis
non sister chromatids of paired chromosomes cross over at chiasmata and break and re-join, swapping alleles

Question 7

monosomy

Answer 7

tuners syndrome
missing a copy of a chromosome

Question 8

trisomy

Answer 8

downs syndrome
extra copy of a chromosome
