# 2
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.
Is This Answer Correct ?    30 Yes 6 No
# 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

AA x aa = Aa x aa
