Flashcards in PreLab Reading Lab 5 Deck (18):
1

asexual reproduction

reproudction by which offspring arise from a single orngaism and inherit genes of that parent only

2

sexual reproduction

prodution of new living organisms by combine genetic info from two idnviidual of different types

3

asexual strategies

cloning, binary fission, buddidng, parthenogenesis, fragmentation, spore formation

4

cloning

make identical copy

5

binary fission

divison in half- most common form of reprodufion in prokaryotes some single celled eukaryotes

6

budding

new organism develops from an outgrowht/bud due to cell divison at one particular site, new organism remains attached as it gows- separte from parent orgnaisms only when mature

7

parthenogenesiis

form of reproduction where ovioum develops into new individual without fertiliztion, no fertilization with amle

8

fragmentation

organism split into fragments each fargment develop into mature, fully grown individual clones of orngianl organisms

9

spore formation

sporangia contacining spores, organism breaks into number of peices/sports devlepo into organism like parent form

10

sexual strategies

external fertlization, internal fertlization, sproe formation, hermpahroditism, self incompatibility, isogamy, anisogamy, oogamy

11

external fertlization

M's sperm fertlizing female's egg outside f's body

12

internal fertailization

occurne of internal insemination as model of combining sperm and egg

13

spore formation

multipple fission organism breaks into number of peices developing into oranigsm like parent form

14

hermaphroditism

organismwith reproductive organis normally associate with both m and f sexes

15

self incompatibility

several genttic mechinsms in angioseprms wihich prevent self rfertlization

16

isogamy

gametes with similar morphology similar differ in general only in in allele expression in one plus matng type regions

17

anisogamy

reproduction by union/fusion of two differnig gametes in size/motility

18

oogamy

form of anisogamyF gamete significantly larger than M gamete and is non otile
