Lec 1 Mendelian Peas

Question 1

Genetics is the study of

Answer 1

inheritance and variation in traits and heritable trait variation

Question 2

Genetics matters bc

Answer 2

behavior, agriculture, conservation, origins, diseases, and biotechnology

Question 3

How to determine gene function

Answer 3

study trait variation in natural populations

study novel mutations

Question 4

Phenotype to

Answer 4

genotype

Question 5

Forward gentics:

Phenotype to genotype collects mutants with

Answer 5

phenotype of interest

Question 6

Forward gentics

Phenotype to genotype cross mutants to

Answer 6

wild type to determine how many genes are involved and dominance

Question 7

Forward Gentics:

Phenotype to genotype ID the mutants and

Answer 7

deduce the molecular functions of the genes

Question 8

Forward genetics:

Phenotype to genotype deduce how the

Answer 8

gene interacts with other genes to control the trait

Question 9

The seven phenotypic pairs studied by Mendel

Answer 9

round or wrinkled ripe seeds

Yellow or green seeds

purple or white petals

inflated or pinched ripe pods

green or yellow unripe pods

axial or terminal flowers

long or short stems

Question 10

Cross pollination

Answer 10

transfer of pollen with a brush and pollinate the other plant == self pollination?? check notes

Question 11

Selfing

Answer 11

transfer pollen to stigma

Question 12

Mendel’s crosses resulted in speific

Answer 12

phenotypic ratios

Question 13

Mendel’s first law

Answer 13

law of equal segregation

Question 14

a hereditary factor, a gene controls

Answer 14

trait

Question 15

the parent has a pair of the

Answer 15

gene

Question 16

the gene comes in

Answer 16

two forms a allele

Question 17

an individual may be

Answer 17

homozygous or heterozygous for an allele

Question 18

Homozygous

Answer 18

2 copies of same allele

Question 19

Heterozygous

Answer 19

1 copy of one allele

other parent has other copy of an allele

Question 20

in a heterozygote the allele that determines the phenotype is

Answer 20

dominant and the other is recessive

Question 21

the members of a gene pair separate equally into

Answer 21

gametes during meiosis

gametes contain one member of the gene pair

Question 22

gametes fuse randomly to form

Answer 22

zygotes

Question 23

Zygotes

Answer 23

a fertilized egg the first cell to develop into a progeny individual
