Question

Is test cross used to determine genotype of recessive treit?

Answer 1

Test crosses are used to test an individual's genotype by crossing it with an individual of a knowngenotype. Individuals that show therecessive phenotype are known to have a homozygous recessive genotype. Individuals that show the dominant phenotype, however, may either be homozygous dominant orheterozygous.

Answer 2

No.Test cross is used to determine the genotype of the dominant trait.

It helps us to find the genotype (homozygous or heterozygous) of the dominant trait.

Test cross is a cross done between an F1 hybrid and it's recessive parent.It helps us to find whether the F1 hybrid is a homozygous dominant or heterozygous dominant.
