उत्तर
A cross used to verify the unknown genotype of the F1 hybrid is a Test cross.
Explanation:
The crossing of an F1 progeny with a double (homozygous) recessive parental progeny is done in order to determine whether the progeny is homozygous or heterozygous for a character under consideration. This is called a test cross. It was first introduced by Gregor Mendel. Those that are heterozygous will have one dominant and one recessive allele individuals and those that are homozygous dominant will have two dominant alleles, and those that are homozygous recessive will have two recessive alleles.
