PRINCIPLES OF INHERITANCE

Question 1

term given by
genetics
pure line
gene
homo/hetero/hemizygous
allele
phenotype/genotype

Answer 1

bateson
johanson
johansen
bateson
bateson
johansen

Question 2

basis of inheritance
basis of heridity
base number also called
genotype controle phenotype and vise versa
father of modern genetics

Answer 2

factors/chormosome/gene(physical baisis of inheritance)/dna(chemical basis )/
inheritance
no of chormosome in a set (x)
also called monoploid
atavisims also called reversimss
viseversa not true
willium bateson experimet on sweet pea

Question 3

what is a gene
allele
hemizygous
mendel experiment

Answer 3

the segement of dna which expreses the charecter — code for charecter
slightly different foe=rms of a different gene present on same loci on the homologous chromosome– code for tall/short
like xy chromrosome in humans
extensuion of hybridization experiment of knoght and groose

Question 4

chromosome terme given by
what is genome
alleleic and non allelic gene pair

Answer 4

waldeyar
haploid set of the chromosomes
i.e. 2 genome in human each contain 23 chromosomes
allelic aa/Aa
non alleleic AB

Question 5

FORMULAS
homozygous means

Answer 5

write o a paper
homoxygous means only one gamete prtoduced by them

Question 6

premendel law

Answer 6

law of genmplasm
somatoplasm and germplasms
only gene of germplanst is passed to progeny i.e.
by wieseman by rat tail experiment

Question 7

medndel conducted artificial and cross ussing
initially selecterd how many varities
how many traits/allele/charecter/gene/plants
dominant trait in flower colour
s.blixit distribution
punnite square
hugo di varie publiched mendel work in flora

Answer 7

true / pure breeding line- which have gone through selfing for several generatuion
initailally 34- then 22 then 14
14 trait
14 plants/allele
7 charecter/gene
voilet
1-flower colour , seed colour
4-flowerposition,stem height ,pod shape
5-pod colour
7-seed shape
all possoble genotype writteen in squares only

Question 8

recipocal cross in necular and cytoplasmic inheritance
bynominal equation
who gave shape to these laws

Answer 8

make female genotype male nad male genotype is made female
nuclear me same results and cytoplasmic me female is domionant as most of the chromomosome are from femal there is no 50/50 ration
carlcovens

Question 9

exception to mendelisms (i gene one charecter out of which one is dominat and other is ressisove)
universal law among the three
back cross(different from recipocal cross)
test cross ration

Answer 9

incomplete dominance
co dominance
multiple allilisms
pleotropy
polygenetic inheritance
2nd law is universal law of segegration and purity of gammete s
test and out cross of f2 generation with f1 genetation
1:1 (monohybrid) 1:1:1:1 (dyhybrid cross)

Question 10

incomplete dominance and co dominance
moslty domonant gene are always the modfifed genes

Answer 10

incomplete -dont resembel any of the parents (quantatitive way)
ex . antirrhinimu,dog flower , snapdragon ,miriblis jalapa (4 o clock flower),starch grain in pisum
co domonance resimble both of the parents
ex sickel cell anemia,abo blood grp,hair colour in cattle
modifed allele can be domonamnt or resccive
but mostly mutation lead to normal/less efficent genes which also code for dominant

Question 11

some times reccesive gene can also be wild /original true /flase
other examoke od abo blood group

Answer 11

yes abo blood grp o allele is reccisive and wild also
raddit coat,ey ecolour in dorsoplilia,self incomplatiblity on maize and tobacco

Question 12

pleotropy of pea seed is
absolute , sub, delayed letality exaple

Answer 12

incomplete domonance for intermediate size of seed on complete dominace on
absolute -embryo death .yellow mouse ,haemophilic female
sub lethality- sickel cell anemia
delayed lethality -huntingtons dissise

Question 13

more no of recomninat/parental in f2 genetation

Answer 13

recombinant

Question 14

product rule is also called , based on
interaction of one gene = intragenic/interalliic
inter genic interiaction non allicic

Answer 14

law of independent assortment based on dihybrid cross , rest 2 are based on mono hybrid cross
non allilic inter genic interaction
supplimentary gene -when both dominant then only fully charecter expressed (purple) complementaary also
batson and punnete sweetpea
duplicate gene - capsella / shephard purse when any othe two is dominant ek
top shaped when both reccisive and tringula shaped when any of them is dominant
epistasi
dominant episatis ka example is cucurbitta pipo flower and summer squash 12:3:1
(white,yelloe,green)
Wy white
wY YELLOW
WY WHITE
wy green

Question 15

kernel colour in what , colour of wheat variation
how many polygene
what is the ratio

Answer 15

kernal colour discovered by nilson ehle
also discovered the tobacco height variation
2 pair of polygene
1;4;6;4;1 —– 15:1 red and whight
in f2 intermediate are more thean parental (parental are pure red and pure white)
davanport brothers discovered the human colour varitation

Question 16

huam skin variation have how many pair of polygene
negroo are -____
ration is ___
other quantaiive variation
all formulas

Answer 16

it have 3 pair of polygene and 6 polygene in total
cob lenght in maize
corolla lengh in tobacco
human height
genotype - 3n
phenotyoe (2n+1)
contributation of one gene - max-min/no of polygene
remeber - only dominant are contrubuting and ressisive are non contributing
and count no of domoonant gene and multiple with contrubution and add it with
all ressisive gene weight

Question 17

mendel also worked with ___ but failed why

Answer 17

lablab broad bean and jawkweed(hericium)
absence of pure line in them and parthenogenesis

Question 18

in cti study was maid by whom on what
used which law to explain men delisms

Answer 18

sutton and bovery on meoisis
used chromosomal therory to explain mendel law

Question 19

what sutton and boveri suggested

Answer 19

they suggested that pairing and seperation of a pair of chromosome will lead to pairing and seoeration of the fcator they carried

Question 20

difference between muller and miller
female dorsophilia have ovipositor no of chromosome
many type of heridity variation canbe seen with a hight power microscope

Answer 20

father of actinobiology muller
experiment electrode discharge s.l miller 1953
8 chromosomes out of which 2 are sex
nooo, low power microscope

Question 21

linkage group definiation
y chromosome are ____ small or large
y gene carry tdf which code for sry
gene present on exclusively on y chr is called

Answer 21

gene present on the same chromosome are called linkage group
y chromosome are distintly small
false uchromosome carry sry which code for tdf
holandric gene
or y linked gene

Question 22

barr body formula
and meaning

Answer 22

only prenent in femal esomatic cells
all x chromo except on in the somatic cells are inactive
heterochromatized ,densley linked and coloured
