Meiosis and Mendelian Genetics

Question

Sexual reproduction requires the production of gametes containing half the chromosomes of the parent

Answer 1

Chromosomes of the same length and centromere position with genes for the same characteristics

Answer 2

Chromosomes of the same length and centromere position with genes for complimentary characteristics

Answer 3

Chromosomes of the different length/ centromere position with genes for the same characteristics

Answer 4

Two identical replications

Answer 5

Three identical replications

Answer 6

Of different chromosomes

Answer 7

Of the same chromosomes

Answer 8

Replication

Answer 9

Transcription

Answer 10

DNA degredation

Answer 11

Meiosis I- Sister chromatids separate Meiosis II- Homologous chromosomes separate

Answer 12

Meiosis I- Homologous Chromosomes separate Meiosis II- Sister chromatids separate

Answer 13

Bouquet formations

Answer 14

Rabl formations

Answer 15

Spine formations

Answer 16

Heterochromatin

Answer 17

Homochromatin

Answer 18

Chromosome pairing

Answer 19

Chromosome synapsis

Answer 20

Chromosome recombination

Answer 21

Rabl formations

Answer 22

Lewis formations

Answer 23

Rabl formations

Answer 24

Achiasmate

Answer 25

Non exachange

Answer 26

Holds sister chromatids together

Answer 27

Allows chiasmata to occur

Answer 28

Counteracts microtubule pulling force until the crossover is complete

Answer 29

Increases genetic diversity

Answer 30

Prevents mistakes (i.e. incorrect separation)

Answer 31

Increases efficiency of microtubule separation

Answer 32

Sister chromatids remaining together and travelling to the same pole

Answer 33

The exchange of DNA between homologous chromosomes

Answer 34

Sister chromatids separating and travelling to opposite poles

Answer 35

Monoferrin

Answer 36

Monobindin

Answer 37

Microtubules attach and release separase

Answer 38

Separase is released during chiasmata

Answer 39

Separase is transcribed in the nucleus and diffuses to homologous chromosomes

Answer 40

Between sister chromatids

Answer 41

At the centromere

Answer 42

They are separated away from each other to opposite poles, so each gamete has only 1 allele, giving a ratio of 2:2 in the gametes

Answer 43

They are not separated and go to the same pole, so each gamete has two alleles, giving a ratio of 1:1 in the gametes

Answer 44

They are separated to the same poles, so each gamete has two alleles, giving a ratio of 2:2 in the gametes

Answer 45

Only random mating and gene flow

Answer 46

No selection

Answer 47

No mutation

Answer 48

No meiotic drive

Answer 49

That alleles are separated from each other so each gamete will possess one allele

Answer 50

The order in which the homologous chromosomes line up at the equator is completely random with respect to each other

Answer 51

Genes are found on the same chromosome

Answer 52

The clustering of telomeres prevents genes from separating

Answer 53

The occurrence in members of a population, combinations of linked genes in non-random proportions

Answer 54

A bivalent

Answer 55

A bouquet formation

Answer 56

Linkage disequilibrium

Answer 57

Homologous Chromosomes

Answer 58

Sister chromatids

Answer 59

Recombinant chromatids
