Question 1

Incomplete Dominance

Answer 1

Blended traits

Question 2

Chrominance

Answer 2

Both traits expressed

Question 3

Multiple Alleles

Answer 3

multiple traits coded gene for a single trait

Question 4

Polygenic Traits

Answer 4

traits controlled by multiple gene

Question 5

Environment and gene expression

Answer 5

environment decides weather a trait is turned off or on

Question 6

Mendel’s experiment can not predict what??

Answer 6

incomplete dominance, codominance, Multiple alleles, polygenic traits

Question 7

Incomplete dominance example

Answer 7

Flower/clothing color

Question 8

codominance example

Answer 8

speckled color from solid colors

Question 9

Multiple alleles

Answer 9

blood type, fur

Question 10

polygenic traits

Answer 10

variety of skin color

Question 11

In complete dominance, the heterozygous phenotype lies

somewhere between the two homozygous phenotypes.

Answer 11

Incomplete dominance: it in the middle/rotating/ messing up the solid pattern so its a blended trait

Question 12

Multiple alleles but…

Answer 12

few are expressed for each gene

Question 13

Genotype

Answer 13

Gene (letters, ex: aa,Aa,AA)

Question 14

phenotype

Answer 14

trait (color, size)

Question 15

complete dominance

Answer 15

only dominant masks

Question 16

Multiple alleles vs polygenic alleles

Answer 16

Multiple Alleles: controlled by one gene with few alleles

Polygenic traits: controlled by multiple genes and many alleles

Question 17

organism’s phenotype

Answer 17

results from its genotype and its environment

Question 18

depending on environmental conditions

Answer 18

Some genes produce variable traits

Question 19

homozygotes

Answer 19

pure

Question 20

heterozygous

Answer 20

mixed

Question 21

genes are inherited from which parent

Answer 21

female

Question 22

polygenic inheritance

Answer 22

the heredity of complex characters that are determined by a large number of genes, each one usually having a relatively small effect.
