THEME 4A AND 4B

Question 1

ANTHER

Answer 1

MALE PARTS

Question 2

STIGMA

Answer 2

FEMALE PART OF FLOWER

Question 3

PRODUCT RULE

Answer 3

TWO INDEPENDENT EVENTS OCCURRING IN SUCCESSION

• heads = 1/2
• tails= 1/2 probability

2 heads: 1/2 x1/2 =1/4 probability you will achieve 2 heads in succession

Question 4

SUM RULE

Answer 4

TWO DIFFERENT!!! EVENTS PRODUCING SAME OUT COME

HEADS THEN TAILS OR TAILS THEN HEADS

1/2 X1/2 OR 1/2 X1/2

=1/4X2
=1/2

Question 5

LAW OF INDEPENDENT ASSORTMENT

Answer 5

OCCURS IN METAPHASE 1 MIEOSIS

Question 6

LAW OF SEGREGATION

Answer 6

OCCURS IN ANAPHASE 1 MEIOSIS

Question 7

HYPOMORPHS (LESS EFFICIENT)/AMORPHS(ABSENT)

Answer 7

LOSS OF FUNCTION MUTANT ALLELES

Question 8

HYPERMORPHS

Answer 8

GAIN OF FUNCTION MUTANT ALLELES

Question 9

INCOMPLETE DOMINANCE

Answer 9

INTERMEDIATE

Question 10

CODOMINANCE

Answer 10

BOTH TRAITS EXPRESSED
EQUAL EFFECTD
EXHIBITS BOTH!!! HOMOZYGOTE PHENOTYPES

Question 11

NORM OF REACTION

Answer 11

ANY GRAPH THAT DEPICTS HOW A RANGE OF ENVIRONMENT AFFECTS PHENOTYPE

Question 12

POPULATION GENETICS

Answer 12

STUDY OF EVOLUTION OF DISCRETE TRAITS (TRAITS YOU CAN DIFFERENTIATE FROM ONE ANOTHER, EITHER THIS OR THAT)

Question 13

QUANTITATIVE GENETICS

Answer 13

STUDY OF EVOLUTION OF CONTINUOUS TRAITS

Question 14

HOW ARE MUTATIONS RANDOM

Answer 14

THEY OCCUR REGARDLESS OF WHETHER THEY ARE BENEFICIAL TO THE ORGANISM

Question 15

HOW ARE MUTATIONS NOT!!! RANDOM

Answer 15

EACH TYPE OF MUTATION DOES NOT!!! OCCUR WITH EQUAL PROBABILITY

Question 16

FIXED ALLELE

Answer 16

WHEN ONLY ONE POPULATION EXHIBITS ONE ALLELE

Question 17

3 WAYS TO MEASURE GENOTYPE OR ALLELE FREQUENCIES

Answer 17

COUNTING OBSERVABLE TRAITS
GEL ELECTROPHORESIS
DNA SEQUENCING

Question 18

POLYMORPHISM

Answer 18

TWO OR MORE DIFFERENT PHENOTYPES EXIST IN THE SAME POPULATION OR SPECIES

Question 19

DARWIN’S FOUR POSDTULATES

Answer 19

INDIVIDUALS WITHIN A SPECIES VARY

SOME VARIATION IS HERITABLE

MORE OFFSPRING ARE PRODUCED THAT WILL SURVIVE

SURVIVAL AND REPRODUCTION LINKED TO PHENOTYPIC VARIATION

Question 20

EVOLUTION BY NATURAL SELECTION WILL NOT OCCUR WHEN (3)

Answer 20

NO VARIATION

TRAIT NOT HERITABLE

VARIATION HERITABLE, BUT NOT LINKED TO SURVIVAL OR REPRODUCTION (NO FITNESS CONSEQUENCE)

Question 21

EVOLUTIONARY MECHANISMS (4)

Answer 21

NATURAL SELECTION

SEXUAL SELECTION

GENETIC DRIFT

GENE FLOW

Question 22

NULL HYPOTHESIS FOR EVOLUTION

Answer 22

NO CHANGE IN GENE FREQUENCIES OVER TIME

HARDY-WEINBERG EQUILIBRIUM

Question 23

5 CONDITIONS FOR HARDY-WEINBERG EQUILIBRIUM

Answer 23

1) POPULATION MUST BE LARGE
2) NO MUTATION
3) NO GENE FLOW
4) NO SELECTION
5) RANDOM MATING

Question 24

3 PREDICTIONS IF HWE IS IN EQUILIBRIUM:

Answer 24

1) ALLELE FREQUENCIES ARE CONSTANT
2) GENOTYPE FREQUENCIES ARE CONSTANT
3) THESE EQUILIBRIUM FREQUENCIES CAN BE REACHED IN ONE GENERATION OF RANDOM MATING
