  1. Top cross

  2. Inter cross

  3. Test cross

  4. Batch cross


Solution

The correct option is C

Test cross


The cross between a suspected heterozygote with the recessive parent is called test cross. This cross basically helps to confirm if the organism in question is homozygous or heterozygous for the dominant allele.
An intercross is an organism that is the offspring of genetically dissimilar parents or stock; especially offspring produced by breeding plants or animals of different varieties, breeds, or species.
Top cross is a cross between a superior or purebred male and inferior female stock to improve the average quality of the progeny.
