peas

what did the monohybrid cross result in

A

f1 round seeds,
f2 wrinkles (3:1) ratio
mating between two parents w diff genotypyes, hybrid makes single trait

Q

principle of segregation

A

developed by mendel cuz of 3:1
- two members of gene pair must seperate in two diff gamete cells during fertilization

17
Q

what did dihybrid cross deterine

A

whether alleles seperate togeter or independent

18
Q

with dyhbrid cross what two hypthesis did mendel test

A

independent assortment and dependent assortment

19
Q

dependent assortment

A

allele depends on another alleles to transmit

20
Q

independent assortment

A

diff genes are transmitted independently of each other

21
Q

what did mendels results support

A

principle of independent assortment

22
Q

punnet square of dihybrid gene results in and confirms what

A

4 possible phenotypes in ratio of
9:3:3:1
alleles of diff genes are transmitted independently

23
Q

did test cross also confirm principle of independent assortment

A

yes

24
Q

What is the chromosome theory of inheritance

A

came out of Sutton and boveri’s observation of meiosis

25
Q

where are genes located on chromosomes

A

locus

26
Q

what stage do alleles seperate physically

A

meiosis 1 ==> principle of segregation

27
Q

why do genes of diff traits assort independtly of one another during meiosis 1

A

cuz they @ diff nonhomolougous chromosomes

explains principle of independent assortment

28
Q

testing chromosome theory of inheritance

what was the model organism for genetics

A

DROSOPHILA MELANOGASTER (fly)

29
Q

Morgans first goal to indentify diff pheno

A

1_ wild type

30
Q

WHAT IS WILD TYPE

A

most common phenotype for each trait

other phenotypes arise by mutatuon

31
Q

What are Mutants

A

individuals with traits caused by mutations

32
Q

drosophila melangaster

what are red eyes in fruit flies

A

wild type

33
Q

drosophila melangaster

what are white eyes in fruit flies

A

mutation

34
Q

what did morgan mate

A

wild type femle with mutant male

35
Q

after morgans reciprocal cross with mutanyt male and wild type, what result

A

f1 female had red eyes, f1 mle had white eyes

suggested relationship between gender and inheritance of eye color in dr

36
Q

what did stevens studie at same time of fruit flies (morgan)

A

he studied insects

37
Q

what did stevens discover

A

sex chromosomes

38
Q

sex linkage

A

genes being on either sex chromosomes

explained recirpocal cross

39
Q

linkage

A

explain why in some experimental crossed f2 prodegy did not conform to 3:1 or 9:3:3:1 ratio

40
Q

Linkage

A

tendency of genes to be inherited together because they are on the same chromosome

41
Q

what does linkage refer to

A

two or more genes located on the same chromosome

42
Q

sex linkage

A

says nothing about location of gene relative to another
