I still do not understand How to get the F2 Generation

Post by Redspart1 » Mon Apr 12, 2010 10:37 pm

Can someone explain to me better how to get the F2 generation after i get the F1? I am going to try to do the F1 and if someone would tell me if i did that wrong to, that would be a big help. Yes this is Monohybrid Cross

....A...a....B....b
A..AA..AA..AB..Ab
a..Aa..aa..Ba..ab
B..AB..Ba..BB..Bb
B..AB..Ba..BB..Bb

The colors are what I got in the cross

you're doing it worng

I guess you have AaBb and AaBB, right?
you should have AB, Ab, aB and ab in one and AB and aB in the second and thus the square will look a little different ;)

Cis or trans? That's what matters.

its not a monohybrid crosss.... in monohybrid cross single trait IS crossed to..
as
(HERE A, B CORRESPONDS TO A COMMON PHENOTYPE LIK TALL N DWARF)

AA X BB
AB- F1
FOR F2 GENERATION
AB X AB
FOR EACH GAMETES WILL BE A AND B
SO IT GOES LIK THIS

A B
A AA AB

B AB BB
THESE FORMS UR F2 GENERATION..
WAT U R WRITING IS AN EXAMPLE OF DIOHYBRID CROSS, IN WHICH TWO TRAITS ARE CROSSED..
AS
AABB X aabb
where A,a corresponds to one phenotype and B,b to another trait..
I HOPE NOW U CAN DIFFERENTIATE B/W MONO N DIHYBRID CROSS..
ALSO HW TO MAK F2 GENERATION..
U SHUD ONLY KNO HOW TO MAK GAMETES.. DATS IT.. REST IS DONE EASILY....

if A and B are for different traits, you can't have only A or only B :roll:
