Question

The plants in F1 (TTGG x ttGG) were allowed to undergo self-pollination. The expected phenotypic ratio to be obtained is? Show me how please :)

Answer 1

Hey there!

Answer 2

Hiiiii, please tell me you're familiar with this? :)

Answer 3

So the genotype of the parent plants are TTGG and ttGG Right?

Answer 4

yes

Answer 5

Yep, I am familiar (Thankfully ;))

Answer 6

So, first of all you know the meaning of self pollination ?

Answer 7

Because I have few more questions :p

Answer 8

I think

Answer 9

yes, yes, i do know

Answer 10

ok, now let's have a look real quick on how to work out a punnet square for this question.

Answer 11

well, yeah, that is the problem, i have no idea how to do it in this form. I know how to do for example TT X tt a monohybrid one :p

Answer 12

First of all we will have to find the F1 Generation.

Answer 13

Yes, this one is Dihybrid Cross.

Answer 14

Next Step will be to self pollinate \(\sf F_1\) generation i.e. we will have to perform a cross between tTGG X tTGG

Answer 15

Getting it?

Answer 16

I think we have to perform a cross between TTGG x ttGG

Answer 17

We have to perform a self pollination on the \(\sf F_1\) generation, which will be given by TTGG X ttGG. The \(\sf F_1\) generation will be tTGG

Answer 18

Ahh, okay
