(a) Explain the following terms:
(i) test cross
(ii) monohybrid cross.
(b) In a mango plant the, the allele for bean-shaped seed is r and is recessive to round-shaped seed R. With the aid of a genetic diagram, determine the genotypes of the offspring if:
(i) a homozygous bean-shaped parent with a homozygous round shaped parent;
(ii) a heterozygous bean-shaped parent is crossed with a heterozygous round shaped parent.
(a) Test cross; This is the crossing/mating of an organism of unknown genotype with a homozygous recessive/double recessive organism;to determine the genotype of an organism.
