Question

write benefit of test cross​

Answer 1

Answer:

Test cross is a cross in which an individual with an unknown dominant phenotype is crossed with an individual (parent) homozygous recessive for that trait. Test cross determines whether the dominant character is coming from homozygous dominant genotype or heterozygous genotype. Thus it is more useful than back cross.

Answer 2

Answer:

The purpose of a test cross is to determine if this individual is homozygous dominant or heterozygous. Test crosses involve breeding the individual in question with another individual that expresses a recessive version of the same trait.
