|
of two pure-breeding forms to find out which form of a gene is dominant
|
|
between two unknown forms to determine their genotypes
|
|
between an offspring and its parent
|
|
of an F1 hybrid to an individual that is homozygous recessive
|
|
of two F2 individuals to produce an F3 generation
|
Detailed explanation-1: -A cross between F1 hybrid and its homozygous recessive parent is called Test cross.
Detailed explanation-2: -When the cross is between an F1 hybrid with the homozygous recessive parent, it is known as a Test Cross.
Detailed explanation-3: -∙ The cross between recessive to its hybrid or its F1 plant is called a test cross. ∙ Test cross helps in determining the genotype of the hybrid plant by crossing F1 with the recessive parent.
Detailed explanation-4: -When a progeny of F1 is crossed with the homozygous recessive parent it is called test cross. Such a cross is useful to determine the genotype of an unknown i.e. whether it is heterozygous or homozygous dominant for the trait.
Detailed explanation-5: -c) A test cross is a cross between an individual of unknown genotype or a heterozygote (or a multiple heterozygote) to a homozygous recessive individual.
