Question
what is the difference between back cross and test cross?
 Question Submitted By :: Genetics
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
Test cross is the cross between recessive parent with one of
its progeny.


backcross is the crossing between any of its parents with
progeny.
These tests are done normally to identify homozygosity among
the breeds.

back cross:- it is a cross between f1 individual with one
of its parent genotype.

test cross:-it is a type of back cross between f1
individual and homozygous recessive.

Answer
# 3
Back cross - crossing of hybrid (F1)either of its parents
(dominan / recessive).

AA x aa = Aa x AA / aa

Test Croos - Crossing of F1 with homozygous recessive
parent.

AA x aa = Aa x aa

Answer
# 4
back cross-cross between any of the f1 generation offspring with any one of the two parents either the recessive or the dominant

test cross- cross that is being done between the f1 generation offspring with the recessive parent
This cross is being performed to confirm or check the genotype of f1 generation individual taken as sample for cross
