Answer 25

sure...first we need to make gametes...

Answer 26

How do we make gametes?

Answer 27

see now u have 2 traits t and r rite? both coding for 2 different phenotypes?

Answer 28

lets consider 1st eg for now...

Answer 29

Yes

Answer 30

cool....now to make gametes we need 2 have 1 t and 1 r....whether capital or small...

Answer 31

for eg ill show u 1...lets take this TtRr
the gametes of this would be-TR Tr tR tr...

Answer 32

u need to make combinations in such a way that u have 1 t and 1 r in the gamete...either dminant or recessive depending on the alleles present in parent genotype

Answer 33

u wid me?

Answer 34

Yes

Answer 35

cool...now can u tell me d gametes of other parent Ttrr?

Answer 36

I didn't get this :c how to make gametes :I

Answer 37

ok..lets do it again...see d genotype of parent is Ttrr rite?
now i need 2 make gametes.
gametes in this case are made up of 2 letters...ok?
one should be t and other r either capital or small...can u mak combinations for me using T,t,r,r only? remember u cannot write 2 t's or r's together...

Answer 38

Tr,tr,tR,TR? :I

Answer 39

u r rite about the 1st parent...TtRr..for this these are perfectly correct...

Answer 40

now take a look at Ttrr...in this we do not have R...rite? we only have t,T,r,r
so make gametes using only these letters...

Answer 41

Can I combine capital T with small t?

Answer 42

nope....no same letters together...

Answer 43

Tr,tr,Tr,tr?

Answer 44

correct.....:D so it comes down to 2 gametes rite? Tr and tr...

Answer 45

it is not compulsory that u should get 4 gametes....

Answer 46

Owww I get it now..:3

Answer 47

so now write down d gametes of both the parents for me....
TtRr-
Ttrr-

Answer 48

Tr,TR,tr,tR

For Ttrr=Tr, tr

Answer 50

now clear on how to make d gametes?

Answer 51

Yes, I think!

Answer 52

cool...now lets make d punnet square....this is how u do it
