Flashcards in biology test 3 Deck (13):
1

MATING SYSTEM CLASSIFICATION:
MONOGAMY

-WHEN MALES AND FEMALES ONLY REPRODUCE BETWEEN 1 FEMALE AND 1 MALE.
-NOT VERY COMMON IN NATURE

2

MATING SYSTEM CLASSIFICATION:
POLYGYNY

-DURING BREEDING SEASON, A MALE WILL REPRODUCE WITH MANY FEMALE AND FEMALES WILL ONLY MATE WITH 1 MALE.

3

MATING SYSTEM CLASSIFICATION:
POLYANDRY

-DURING BREEDING SEASON, A FEMALE WITH MATE AND REPRODUCE WITH MULTIPLE MALES AND MALES WILL REPRODUCE WITH NLY ONE FEMALE.
-EXAMPLE; HONEYBEE

4

MATING SYSTEM CLASSIFICATION:
POLYGYNANDRY

-BOTH FEMALES AND MALES MATE AND WILL REPRODUCE WITH MULTIPLE MALES AND FEMALES.
-MOST COMMON MATING SYSTEM

5

WHAT DO MATING SYSTEMS AFFECT?

-AFFECT BOTH THE DIRECTION AND INTENSITY

6

WHAT IS GYNANDROMORPH?

-IT IS WHEN SEX CHROMOSOMES ARE INCORRECTLY DIVIDED SO THEY GET BOTH FEMALE AND MALE SEX GENES.
-VERY RARE

7

SPECIATION

THE ORIGIN OF NEW SPECIES

8

WHAT DOES SPECIALIZATION DO TO POPULATIONS?

SPECIALIZATION IS A PROCESS THAT SETS POPULATIONS ON TWO DIFFERENT PATHS.

9

WHAT DOES SPECIALIZATION DO TO POPULATIONS?

IT EVOLVES THE POPULATIONS SO THAT THEY CAN NO LONGER REPRODUCE WITH EACH OTHER

10

SPECIATIN REQUIRES TWO THINGS. WHAT ARE THEY?

INTERRUPTION OF GENE FLOW AND ISOLATING MECHANISMS

11

THE MECHANISMS OF SPECIALIZATION VARY AS WELL AS THE TIME SCALE.

TRUE

12

BIOLOGICAL SPECIES

GROUP F POPULATIONS WHICH CAN INTERBREED BUT ARE REPRODUCTIVELY ISOLATED FROM OTHER SUCH GROUPS

13

WHAT DO INTERRUPTIONS INTERRPUTIONS OF GENE FLOW MEAN?

ALLES FREQUENCIES CAN CHANGE DRASTICALLY
