Question 1

Autopolyploidy

Answer 1

Doubling of chromosome number

Question 2

Allopolyploidy

Answer 2

2 chromosome sets from 2 related species

Question 3

Translocation

Answer 3

Nonhomologous chromosome exchange

Question 4

Inversion

Answer 4

Chromosome segment inverted, sexual reproduction has low success

Question 5

Primary barrier

Answer 5

Could be habitat, temporal, behaviour. Is usually genetic. Recombination in hybrids produces poor viability

Question 6

Hox genes

Answer 6

Control body segmentation (somites) and limb development

Question 7

Asexual reproduction

Answer 7

Fast but no individual variation= clones
Binary fission
Mitosis of eukarya

Question 8

Binary fission

Answer 8

Of bacteria and archaea.

Haploid circular chromosome/form colonies, filaments

Question 9

Mitosis of eukarya

Answer 9

Haploid or diploid, linear chromosomes, interphase prophase metaphase anaphase telophase cytokinesis, fragmentation, budding, growth, regeneration, pathogenesis.

Question 10

Sexual reproduction

Answer 10

Individual variation through 1) sexual 2) interchromosomal and 3) intrachromosomal recombination

Question 11

Meiosis of some eukarya

Answer 11

Diploid to haploid reduction division, yielding 4 daughter cells: prophase 1: synapsis of homologous chromosomes with crossing over, meiosis 1 and 2

Question 12

Life cycles

Answer 12

Alteration of generation 1) diplobiont: sporophyte meiosis gametic, 2) diplohaplobiont: both, meiosis sporic, haplobiont: gametophyte meiosis zygotic

Question 13

Polypheletic

Answer 13

No common ancestor

Question 14

Parapheletic

Answer 14

Some common ancestors

Question 15

Monopheletic

Answer 15

One common ancestor
