PATTERNS OF DESCENT WITH MODIFICATION

Question 1

the word “species” originates from the latin “kinds” which is a translation of the greek word “___”

Answer 1

eidas

Question 2

pre zygotic isolating mechanisms

Answer 2

geographical
temporal
behavioral
mechanical
gametic

Question 3

post zygoticisolating mecha

Answer 3

hybrid inviability
hybrid sterility
hybrid breakdown

Question 4

potential mates occupy different areas and never come in contacy

Answer 4

geographical isolation

Question 5

different groups are not reproductively mature at the same time

Answer 5

temporal isolation

Question 6

patterns of courtship are different

Answer 6

behavioral isolation

Question 7

differences in reproductive organs prevent interbreeding

Answer 7

mechanical isolation

Question 8

incompatibilities between sperm and egg cell prevent fertilization

Answer 8

gametic isolation

Question 9

fertilized egg fails to develop past early embryonic stage

Answer 9

hybrid inviability

Question 10

hybrids are sterile because gonads develop abnormally

Answer 10

hybrid sterility

Question 11

some hybrids are normal, some are not and weak and die

Answer 11

hybrid breakdown

Question 12

how a kind of organism is created. it occurs when a group within a species separates from other members and creates a different species

Answer 12

speciation

Question 13

modes of speciation

Answer 13

allopatric speciation
peripatric speciation
parapatric speciation
sympatric speciation

Question 14

some members of the population become geographically separated, preventing gene flow

Answer 14

allopatric s.

Question 15

physical barriers make it impossible for members to interbreed, one group is much smaller than the other

Answer 15

peripatric s.

Question 16

the groups evolved to be separate species are geographically neighbors

Answer 16

parapatric s.
