Question 1

Anthers (m)

Answer 1

Male flower part. Hold pollen

Question 2

Stigma (fe)

Answer 2

Female flower part. Gets pollen

Question 3

True breeding is synonymous with

Answer 3

Homozygous

Question 4

F2 Generation

Answer 4

3:1 ratio

3 purple 1 white

Question 5

Alleles are

Answer 5

Inherited from EACH parent

A from mom A from dad= AA

Question 6

Pedigree chart

Answer 6

Human family tree

Question 7

Recessive traits

Answer 7

Attached earlobe. Albino.

Question 8

Recessively inherited disorders (disease)

Answer 8

Genotype is always hh (homozygous recessive)

Question 9

Character

Answer 9

Eye color

Question 10

PHenotype

Answer 10

Physical characteristic (height tall hair long)

Question 11

Allele

Answer 11

Dominant: A, B C
Recessive: a,b,c

Different version of same gene

Question 12

Complete dominance

Answer 12

Dominant allele covers up Recessive allele

Question 13

Incomplete dominance

Answer 13

Blending (red flower+white= PINK)

Question 14

Codominance

Answer 14

Both alleles show up.

An example of codominance is a roan cow where one parent is red and one parent is white. The roan cow has white and red because both alleles are expressed

Question 15

Pleiotropy (pleiotropy alleles: sickle cell disease)

Answer 15

Single gene affecting multiple traits

Question 16

Polygenic inheritance

Answer 16

Multiple genes affect single trait (skin color)

Question 17

Epistasis

Answer 17

Gene @ 1 locus alters phenotypic expression of a gene @ another locus
