Answer 3

dont

Question 4

true polygenetic conditions means

Answer 4

quantitive conditions (genetics)

Question 5

an example of Meristic

Answer 5

how many scales are on a lizard

Question 6

Answer 6

the height or weight of an individual

Question 7

Meristic is something which is __

Answer 7

countable

Question 8

Mensural is something which is __

Answer 8

measurable

Question 9

A bell curve is due to ___ ___ ___

Answer 9

additive genetic variation

Question 10

the intermediate form produces the __ point in the bell curve

Answer 10

tallest

Question 11

T/F: do both Meristic and Mensural fall under quantitive genetics?

Answer 11

True

Question 12

__ __ helped discover that a lot of yields found in plants and animals fall in additive genetic variation

Answer 12

quantitive genetics

Question 13

the most common form produced in quantitative genetics is the __ form

Answer 13

intermediate

Question 14

additive genetic variation is that 1 alleles adds 1 unit of ___

Answer 14

variation

Question 15

how can one calculate the phenotype of an individual

Answer 15

add up units of variation within the individual. 1 unit of variation is added by each allele

Question 16

most yields (milk yield) tends to have which type of genetics associated with it? quantitative or additive

Answer 16

additive

Question 17

Penetrance:

Answer 17

% of the population that shows the phenotype associated with the genotype

Question 18

an example of penetrance: a group of 50 individuals all have the genotype for freckles, but they do not all express the same number of freckles. why?

Answer 18

because of penetrance

Question 19

if most all in the population do show the phenotype for its correlating gene, this is known as __ Penetrance

Answer 19

high

Question 20

expressivity:

Answer 20

the level of expression

Question 21

an example of expressivity: a group of people that all have the genotype for the same disease, but their symptoms vary in how dramatically they are expressed. why?

Answer 21

because of expressivity differences

Question 22

expressivity __ included in genetic testing

Answer 22

isn’t

Question 23

genetic tests allow for ___ medicine

Answer 23

personalized

Question 24

complex trait/rare varient

Answer 24

unique genetic makeup with a unique (rare) genotype

Question 25

complex trait/ common variant

Answer 25

everyone has the same mutation type with basically the same genetic coding for a specific disease

Question 26

you can see genetic variation in symptoms because there are several __ that work together to produce various symptoms

Answer 26

genes

Question 27

allelic variation = different combinations = lots of genetic variation = same disease but the __ ranges from mild to severe

Answer 27

expression

Question 28

regulatory genes can increase/ decrease the __ of the gene which they regulate

Answer 28

expression
