A cross between a homozygous recessive and a heterozygous plant is called:

Explanation

Option B is correct. Yes, a cross between a homozygous recessive and a heterozygous plant is called a test cross. The test cross is a genetic cross between an individual of an unknown genotype and an individual with a homozygous recessive genotype for a particular trait. The purpose of a test cross is to determine the genotype of the individual of unknown genotype. In a test cross, the individual of an unknown genotype is crossed with an individual who is homozygous recessive for the trait in question. If the individual of unknown genotype is homozygous dominant for the trait, then all of the offspring will be heterozygous. If the individual of an unknown genotype is heterozygous for the trait, then half of the offspring will be homozygous dominant, and half of the offspring will be homozygous recessive.
