• B. Test cross
• C. Top cross
• D. Inter cross

Answer 1

The correct option is B

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 a cross when the offspring are from 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 pure breed male and inferior female stock to improve the average quality of the progeny.
